Claims
- 1. A method for forming an input image sequence, said method comprising the steps of:
(a) defining a region of interest, wherein said region of interest is defined in accordance with a detected audio signal; (b) obtaining a higher resolution of said defined region of interest to form a component of the input image sequence; and (c) applying said input image sequence to an encoder.
- 2. The method of claim 1, further comprising the step of:
(d) applying said higher resolution of said defined region of interest to implement a zooming function.
- 3. The method of claim 1, further comprising the step of:
(d) applying said higher resolution of said defined region of interest to implement a compositing function.
- 4. The method of claim 1, further comprising the step of:
(d) defining a non-region of interest; and (e) encoding said non-region of interest at a lower quality.
- 5. The method of claim 4, wherein said region of interest and said non-region of interest are encoded into two separate streams.
- 6. The method of claim 1, further comprising the step of:
(d) encoding said region of interest at a different quality.
- 7. The method of claim 1, further comprising the step of:
(d) changing a resolution of the input image sequence to account for said defined region of interest.
- 8. The method of claim 1, further comprising the step of:
(d) changing a quality of the input image sequence to account for said defined region of interest.
- 9. A method for classifying a block within a current image of an input image sequence, said method comprising the steps of:
(a) detecting an audio signal; (b) associating said audio signal to a block in a current image of the input image sequence; and (c) classifying said block as an important block..
- 10. The method of claim 9, wherein said detecting step (a) detects said audio signal using a plurality of spatially offset microphones.
- 11. The method of claim 10, wherein said associating step (b) associates said audio signal to a block having a speaker.
- 12. A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps comprising of:
(a) defining a region of interest, wherein said region of interest is defined in accordance with a detected audio signal; (b) obtaining a higher resolution of said defined region of interest to form a component of the input image sequence; and (c) applying said input image sequence to an encoder.
- 13. The computer-readable medium of claim 12, further comprising the step of:
(d) applying said higher resolution of said defined region of interest to implement a zooming function.
- 14. The computer-readable medium of claim 12, further comprising the step of:
(d) applying said higher resolution of said defined region of interest to implement a compositing function.
- 15. The computer-readable medium of claim 12, further comprising the steps of:
(d) defining a non-region of interest; and (e) encoding said non-region of interest at a lower quality.
- 16. The computer-readable medium of claim 12, further comprising the step of:
(d) encoding said region of interest at a different quality.
- 17. The computer-readable medium of claim 12, further comprising the step of:
(d) changing a resolution of the input image sequence to account for said defined region of interest.
- 18. The computer-readable medium of claim 12, further comprising the step of:
(d) changing a quality of the input image sequence to account for said defined region of interest.
- 19. A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps comprising of:
(a) detecting an audio signal; (b) associating said audio signal to a block in a current image of the input image sequence; and (c) classifying said block as an important block.
- 20. An apparatus for forming an input image sequence, said apparatus comprising:
an importance map generator for defining a region of interest, wherein said region of interest is defined in accordance with a detected audio signal; an image capturing device for obtaining a higher resolution of said defined region of interest to form a component of the input image sequence; and an input image processing module, coupled to said importance map generator and said image capturing device, for applying said input image sequence to an encoder.
- 21. An apparatus for classifying a block within a current image of an input image sequence, said apparatus comprising:
an audio detector for detecting an audio signal; and an importance map generator, coupled to said audio detector, for associating said audio signal to a block in a current image of the input image sequence and for classifying said block as an important block.
