FIG. 1 is a flowchart illustrating a method for generating effect character according to an embodiment of the present disclosure, which may generate effect characters, the method may be performed by an effect character generating apparatus, which may be composed of hardware and/or software, and may be generally integrated in a device having an effect character generating function, the device may be an electronic device such as a server, a mobile terminal, or a server cluster. As shown in FIG. 1, the method includes the steps of:

S110, transforming an original monochrome character image into a color character image.

Therein, the original monochromatic character image may be a static image filled with a single color in characters, for example: white. A color character image can be understood as a static image in which the characters are filled with color.

In this embodiment, the original monochrome character image may be transformed into a color character image by obtaining position information of each pixel point constituting the character, obtaining color information from a set color bar based on the position information, and using the color information as a final color of the pixel point. In which, the manner of acquiring the color information from the set color bar according to the position information may be to: take the abscissa value or the ordinate value of the pixel point as index information, and acquire the color information from the set color bar according to the index information.

In an example, the original monochrome character image may be transformed into a color character image by: copying the original monochrome character image in multiple copies to obtain a plurality of copied monochrome character images; mapping the characters in the plurality of copied monochromatic character images to different colors, respectively, to obtain a plurality of color images; moving the plurality of color images by at least partially different offsets in the second direction, respectively; color filter overlaying the plurality of shifted color images and the original monochromatic character image to obtain an overlaid image; masking the overlaid image by using the original monochrome character image to obtain a color character image.

For example, the different colors may be colors in red, orange, yellow, green, cyan, blue and purple. The second direction is associated with the ordering direction of the characters in the image, the second direction is longitudinal direction if the ordering direction of the characters is longitudinal direction, and the second direction is transverse direction if the ordering direction of the characters is transverse direction. The offsets of the plurality of color images may be partially different or all different, for example, may gradually increase. Exemplarily, assuming that three monochromatic character images are copied and the mapped colors are red, green, and yellow, respectively, the red character image is shifted by d in the second direction, the green character image is shifted by 2d in the second direction, and the yellow character image is shifted by 3d in the second direction.

The process of masking the overlaid image by using the original monochrome character image may be performed by: aligning the original monochrome character image with the overlaid image, and for each pixel point constituting the character in the original monochrome character image, taking the color of the corresponding pixel in the overlaid image as the color of the pixel point to obtain a color character image. Illustratively, FIG. 2 is a diagram illustrating the conversion of an original monochromatic image to a color character image in the present embodiment. As shown in FIG. 2, the left image is an original monochromatic image, the middle image is an overlaid image, and the right image is a color character image obtained after masking. In this embodiment, the color character is obtained by masking the overlaid image through the original monochrome character, and the smoothness of the generated color character can be guaranteed.

In an example, after transforming the original monochrome character image into the color character image, the step of edge distorting the color character in the color character image to obtain an edge distorted color image is further included.

For example, the edge may be an edge portion that accounts for a certain proportion of the size of the character, which may be 20%-30%, and may be a left side edge, a right side edge, an upper side edge, or a lower side edge. The position of the edge is related to the ordering direction of the characters, and if the ordering direction is longitudinal, the left edge or the right edge is selected, and if the ordering direction is transverse, the upper edge or the lower edge is selected.

In this embodiment, edge distorting the color characters in the color character image may be performed using a custom water moire function, noise interference, or stripe noise image.

In an example, the color characters in the color character image are edge distorted, and the edge distorted color image may be obtained by: obtaining a stripe noise image; disturbing the edges of the color characters in the color character image in a first direction according to the grayscale information of the stripe noise to obtain the edge distorted color image.

For example, the stripe noise image may be an image including a plurality of brightness gradient stripes, the stripes having a certain width and a certain spacing between adjacent stripes. In this embodiment, the stripe noise image can be custom drawn by a technician. The width of the stripes can control the wave width and crest spacing of the distortion, and the grayscale information can control the crest height of the distortion.

For example, the first direction is associated with the ordering direction of the characters, the first direction is the transverse direction if the ordering direction is the longitudinal direction, and the first direction being the longitudinal direction if the ordering direction is the transverse direction. The disturbing the edges of the color characters in the color character image in the first direction according to the grayscale information of the stripe noise image may be understood as: changing the first direction coordinate values of the color characters edge pixel points according to the grayscale information of the stripe noise image, thereby achieving distorting of the character edges. In this embodiment, the color character is edge distorted by the stripe noise image, and the adaptation of the distorting can be improved.

In an example, disturbing the edges of the color characters in the color character image in the first direction according to the grayscale information of the stripe noise image, to obtain the edge distorted color image may include: aligning the stripe noise image with the color character image; acquiring, for each pixel point of the edge portion of the color character, grayscale information of the pixel point aligned with the pixel point in the stripe noise image; accumulating the grayscale information with the coordinate value of the pixel point in the first direction to obtain coordinate value of the disturbed pixel point in the first direction, to obtain the edge distorted color image.

For example, the grayscale information may be characterized by a value of any one of RGB channels, or by an average value of three channels of RGB. For example, for each pixel point of the edge portion of the color character, the first direction coordinate value of the pixel point is accumulated with the grayscale value of corresponding pixel point of the pixel point in the stripe noise image to obtain the disturbed first direction coordinate value, the second direction coordinate value is kept unchanged, and finally the pixel point is moved to a position corresponding to the disturbed first direction coordinate value and the second direction coordinate value, thereby obtaining the edge distorting image. Illustratively, FIG. 3 is a diagram illustrating edge distorting of color character in this embodiment. As shown in FIG. 3, the left image is a stripe noise image, the middle image is a color character image, and the right image is an edge distorted color image obtained by disturbing the left edges of the characters in the color character image by the stripe noise image. In this embodiment, the edges of the color characters are disturbed in the first direction based on the grayscale information of the noise interference image, which can improve the efficiency of generating the edge distorted color image.

S120, magnifying a set edge in the color character image in a first direction to obtain a stretch effect image.

For example, the set edge may be an edge portion that accounts for a certain proportion (may be 20%-30%) of the size of the characters, and may be a left side edge, a right side edge, an upper side edge, or a lower side edge. The position of the edge is related to the ordering direction of the characters, the left edge or the right edge is selected if the ordering direction is longitudinal, and the upper edge or the lower edge is selected if the ordering direction is transverse. Magnifying the set edge in the color character image in the first direction can be understood as: magnifying the set edge in the first direction by a set factor, keeping the second direction unchanged to obtain a stretch effect image. The principle of image magnification may be implemented in any manner known in the art and is not intended to be limiting herein. In this embodiment, the stretch effect image exhibits a “ribbon” effect.

In one example, magnifying a set edge of the color character image in the first direction to obtain the stretch effect image may be by magnifying a twisted edge of the edge twisted color image in the first direction to obtain the stretch effect image.

For example, the entire region or part of the region of the twisted edge is magnified by a set factor in the first direction while the second direction is kept unchanged to obtain a stretch effect image. Illustratively, FIG. 4 is an example of obtaining a stretch effect image in this embodiment. As shown in FIG. 4, the left image is an edge distortion color image and the right image is a stretch effect image.

In an example, after obtaining the stretch effect image, further including: hybrid overlaying the original monochromatic character image with the stretch effect image, to obtain an overlaid stretch effect image.

For example, hybrid overlaying the original monochromatic character image with the stretch effect image may be understood as overlaying monochromatic characters in the original monochromatic character image over color characters in the stretch effect image such that the overlaid stretch effect image exhibits the effect of “monochromatic characters drifting out of a color band”.

For example, the process of hybrid overlaying the original monochromatic character image with the stretch effect image to obtain the stretch effect image may include: blurring the stretch effect image with a first blur degree to obtain a first blurred stretch image; hybridizing the first blur stretch image and the stretch effect image according to a set hybrid rule to obtain a first hybrid image; aligning the characters in the original monochromatic character image with the characters in the first hybrid image, and shifting the characters in the aligned original monochromatic character image by a set offset in the second direction to obtain an overlaid stretch effect image.

For example, the characters of the original monochromatic character image of the overlaid stretch effect image are positioned above the characters of the first hybrid image. The blurring process may be performed by performing a double-layer Gaussian blurring process and a downsampling process on the stretch effect image, thereby obtaining a first blurred stretch image. The hybrid rule may be a hybrid ratio of pixel values or color values of the first blurred stretch image and the stretch effect image, the hybrid ratio may be unchanged or changed according to a certain rule. For example, when the two images are hybridized, the pixels from one edge to the other edge are hybridized at the same hybrid ratio, or the hybrid ratio is gradually changed from a first setting value (e.g., 1) to a second setting value (e.g., 0) from one edge to the other edge, and then gradually changed from the second setting value to the first setting value.

In this embodiment, by shifting the characters in the original monochromatic charactering image after alignment by the set offset in the second direction, a portion of the color characters below can be exposed and the display effect can be improved. Illustratively, FIG. 5 is an illustration of an example in which an original monochromatic character image is hybridized with a stretch effect image. In this example, the stretch effect image is blurred and then hybridized with the original monochromatic character image to soften the edges of the color band.

In an example, hybridizing the first blurred stretch image and the stretch effect image according to a set hybrid rule to obtain the first hybrid image may include: aligning the first blurred stretch image and the stretch effect image, obtaining first direction coordinate values of aligned pixel points; determining a hybrid ratio according to the first direction coordinate value; hybridizing the aligned pixel points according to the hybrid ratio to obtain a first hybrid image.

For example, the hybrid ratio is the ratio of the stretching effect image to the first blur stretching image, the hybrid ratio may be a value between 0-1. In this embodiment, the correspondence between the first direction coordinate value and the hybrid ratio may be established in advance. Exemplarily, taking the stretching effect image obtained in FIG. 4 as an example, the correspondence can be established by dividing the image into three sub-regions in the left-to-right direction, the three sub-regions being at a ratio of 20%, 10% and 70%, respectively, wherein the hybrid intensity is gradually changed from 1 to 0 from left to right in the first sub-region, the hybrid intensity is gradually changed from 1 to 1 from left to right in the second sub-region, and the hybrid intensity is kept unchanged at 1 in the third sub-region. For example, the manner of hybridizing the aligned pixel points according to the hybrid ratio may be to hybrid color values (RGB) of the pixel points according to the hybrid ratio. Exemplarily, as shown in FIG. 5, the left image is the first blurred stretch image after blurring, the middle image is the first hybrid image after hybridizing the first blurred stretch image and the stretch effect image, and the right image is the stretch effect image after hybrid overlaying the characters in the original monochromatic character image with the first hybrid image. In this embodiment, the hybrid ratio is determined according to the first direction coordinate value, and the smoothness of the first hybrid image can be improved.

In an example, hybrid overlying the original monochromatic character image and the stretch effect image to obtain the stretch effect image may include: blurring the stretch effect image with a second blur degree to obtain a second blurred stretch image; hybridizing the first blur stretch image and the second blur stretch image according to a set hybrid rule to obtain a second hybrid image; aligning the characters in the original monochromatic character image with the characters in the second hybrid image, and shifting the characters in the aligned original monochromatic character image by a set offset in a second direction to obtain an overlaid stretch effect image.

For example, the second blur degree is less than the first blur degree. The characters of the original monochromatic character image in the overlaid stretch effect image is positioned above the characters of the second hybrid image. Hybridizing the first blurred stretch image and the second blurred stretch image according to the set hybrid rule to obtain the second hybrid image may include: aligning the first blurred stretch image and the second blurred stretch image, obtaining first direction coordinate values of aligned pixel points; determining a hybrid ratio according to the first direction coordinate value; hybridizing the aligned pixel points according to the hybrid ratio to obtain a second hybrid image. In this embodiment, the smoothness of the second hybrid image can be improved by hybridizing the two blurred images according to a set hybrid rule.

S130, acquiring a plurality of set noise images, and disturbing pixel points in the set region of the stretch effect image in the second direction respectively according to the plurality of set noise images to obtain a plurality of effect character images.

For example, the set region includes a stretch region, that is, the set region includes a stretch region and a portion of a character region. The set noise image may be a Tyson polygon noise or a Voronoi Noise. The second direction may be a direction perpendicular to the first direction. Disturbing the pixel points in the set regions of the stretch effect image in the second direction respectively according to the plurality of set noise images may be understood as: changing the second direction coordinate values of the pixel points in the set regions according to the grayscale information of the set noise images, so that the set regions are distorted in the second direction.

It will be appreciated that the stretching region may be the operating region corresponding to the magnifying operation of the set edge.

For example, acquiring a plurality of set noise images, and respectively disturbing the pixel points in the set region of the stretch effect image in the second direction according to the plurality of set noise images to obtain the plurality of effect character images may include: aligning the set noise image with the stretch effect image, acquiring, for each pixel point of the set region, grayscale information of the pixel point aligned with the pixel point in the set noise image; and accumulating the grayscale information and the coordinate value of the pixel point in the second direction to obtain the coordinate value of the disturbed pixel point in the second direction to obtain the effect character image.

For example, the grayscale information may be characterized by a value of any one of RGB channels, or by an average value of three channels of RGB. For example, for each pixel point of the set region, the second direction coordinate value of the pixel point is accumulated with the grayscale value of corresponding pixel point of the pixel point in the set noise image to obtain the second direction coordinate value after disturbing, the first direction coordinate value remains unchanged, and finally the pixel point is moved to a position corresponding to the second direction coordinate value after disturbing and the first direction coordinate value, thereby obtaining the effect character image. Illustratively, FIG. 6 is an example of disturbing the set region in the second direction in the present embodiment. As shown in FIG. 6, the left image is a set noise image, the middle image is a stretching effect image, and the right image is an effect image after disturbing. As shown in FIG. 6, in the effect characters, the set region containing the stretch region is twisted in the second direction. In this embodiment, the “ribbon wiggle” effect can be achieved by using the set noise image to disturb the stretch effect image in the second direction.

In an example, the process of accumulating the grayscale information with the coordinate value of the pixel point in the second direction to obtain the coordinate value of the disturbed pixel point in the second direction may include: determining an accumulated weight according to the distance of the pixel point from the character in the first direction; and accumulating a result obtained by multiplying the grayscale information with the accumulated weight with the coordinate value of the pixel point in the second direction to obtain the second direction coordinate value of the disturbed pixel point.

For example, the accumulated weight is inversely proportional to the distance, i.e., the further the pixel point is from the character in the first direction, the greater the accumulated weight. The accumulated weight may be a value between 0-1. The distance of the pixel point from the character in the first direction may be understood as the distance of the pixel point from the centre line of the character in the second direction. For example, after obtaining the accumulated weight, the accumulated weight is multiplied by the grayscale information, and then the multiplied grayscale information is added to the coordinate value of the pixel point in the second direction, thereby obtaining the coordinate value of the disturbed pixel point in the second direction. In this embodiment, the grayscale information multiplied by the accumulated weight is accumulated with the coordinate value of the pixel point in the second direction to obtain the second direction coordinate value of the disturbed pixel point, and the smoothness of the wiggle can be improved and the sense of frustration at the critical point can be reduced.

S140, splice-coding the plurality of effect character images to obtain dynamic effect character.

For example, the effect character image may be an image in which the set region in the stretch effect image is twisted in the second direction. For example, after obtaining a plurality of effect character images, the plurality of effect character images are splice-coded to obtain a dynamic effect character.

In one example, multiple effect character images may be spliced to obtain a multi-frame image, which is then coded into a moving image, i.e., to obtain dynamic effect character.

In one example, after obtaining the plurality of effect character images, the step of periodically adjusting intensity coefficients of saturation levels of the plurality of effect character images is further included.

For example, each of the effect character images corresponds to time stamp information, and the intensity coefficients of the saturation levels of the plurality of effect character images are periodically adjusted according to time. In this embodiment, periodic adjustment of the intensity coefficients of the saturation of the plurality of effect character images may cause the generated dynamic effect character to exhibit the effect of periodic variations in intensity.

In an example, after obtaining the plurality of effect character images, further including: for each pixel point in the set region, determining index information according to grayscale information of the pixel point and time stamp information of a current effect character image; obtaining the target color from the set color bar according to the index information; replacing the color of the pixel point with the target color.

In this embodiment, the grayscale value may be accumulated with the time stamp information to obtain the index information. That is, the index information may be represented as Uv=(grayscale value+time stamp, 0.5). Where Uv may represent coordinate information on a set color bar. For example, after the index information of the pixel point is obtained, the color corresponding to the index information is obtained from the set color bar, and the color is determined as the target color, and finally the color of the pixel point is replaced with the target color. In this embodiment, the color system of the ribbon can be changed by replacing the color of the pixel point with the target color on the set color bar, thereby improving the “ribbon” display effect.

The method for generating effect characters according to the embodiments of the present disclosure can generate characters of stretch and fly effects, and can improve the smoothness and display effect of the effect characters.
