BRIEF DESCRIPTION OF THE DRAWINGS
The foregoing features of this invention, as well as the invention itself, may be more fully understood from the following description of the drawings in which:
FIG. 1 is a block diagram of a preferred embodiment of an electronic computer system for implementing the current invention;
FIG. 1A is a pictorial diagram of a pyramid match kernel intersecting histogram pyramids formed over local features, approximating the optimal correspondences between the sets' features according to the invention;
FIG. 2 is a diagram showing a pyramid match determines a partial correspondence by matching points once they fall into the same histogram bin;
FIG. 3 is four plots showing various matching characteristics;
FIG. 4. shows plots of pyramid match and L1 embedding comparison on bijective matchings with equally-sized sets and partial matchings with variably-sized sets;
FIG. 5 is a plot showing a comparison of object recognition matching techniques;
FIG. 6. shows example images where three images are shown for each of 28 objects;
FIG. 7. is a flow chart showing the process steps to implement the invention;
FIG. 8 shows graphs inferring the time of publication for papers from 13 volumes of NIPS proceedings;
FIG. 9 is an example generated with graphics software composed of a silhouette and its corresponding 3-D pose, as represented by the 3-D positions of 15 joint positions;
FIG. 10 are diagrams of various Pose inference results;
FIG. 11 are examples of Pose inference on real images;
FIG. 12 shows an example where partial matching may be difficult;
FIG. 12A shows additional examples where partial matching may be difficult;
FIG. 13 shows examples of explicit feature correspondences extracted from a pyramid matching;
FIG. 14 shows a schematic view of category feature mask inference;
FIG. 15 is a chart showing accuracy of categories learned without supervision, as measured by agreement with ground truth labels;
FIG. 16 is a chart showing recognition performance on unseen images using categories learned with varying amounts of weak semi-supervision;
FIG. 17 depicts an embodiment of the invention for organizing media files;
FIG. 18 depicts an embodiment of the invention integrating other information with the organized files;
FIG. 19 shows a plot of uniformly-shaped partitions in contrast with a plot where the feature space determines the partition;
FIG. 20 is a comparison of optimal and approximate matching rankings on image data;
FIG. 21 shows a number of graphs of new matches formed at each pyramid level for either uniform (dashed) or VG (solid) bins for increasing feature dimensions;
FIG. 22 shows a comparison of correspondence field errors and associated computation times for the VG and uniform pyramids;
FIG. 23 shows a table that shows our improvements over the uniform-bin pyramid match kernel;
FIG. 23A shows a flow diagram implementing a vocabulary guided pyramid matching technique;
FIG. 24 shows a schematic of a pyramid match hashing technique;
FIG. 25 shows pseudocode illustrating the steps to perform the pyramid match hashing algorithm;
FIG. 26. is a plot showing approximation robustness to outliers; and
FIG. 27 shows image retrieval results for Caltech-4 and Caltech-101 databases using PMK hashing.
