Abstract

The invention provides devices and methods that process images. The invention processes a received signal representing information of texture and information of an image, which has the texture removed from at least one region. The image information is encoded to obtain encoded information of the image. An output signal is generated representing the texture information and the encoded image information. In another embodiment, the invention synthesizes texture based on the received texture information, decodes received image information, which is encoded, to obtain a decoded image, and then maps the synthesized texture onto the decoded image.

Claims

1. A method comprising:

receiving a signal indicative of an encoded image and texture information associated with the encoded image;

decoding the signal, to yield a decoded signal of a decoded image;

synthesizing a new texture for the decoded image based on the texture information; and

mapping the new texture onto the decoded signal of the decoded image.

2. The method of claim 1, further comprising:

identifying a region of the encoded image having a color similar to a substitution color.

3. The method of claim 2, wherein the texture information is associated with the region.

4. The method of claim 3, further comprising:

mapping the new texture based on the texture information into the region.

5. The method of claim 1, wherein the texture information is received in a different channel than the signal.

6. The method of claim 1, wherein the new texture has distinct dominant texture orientation.

7. The method of claim 1, further comprising outputting a new signal representing the signal with the new texture mapped onto the decoded signal.

8. A system comprising:

a processor; and

a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;

receiving a signal indicative of an encoded image and texture information associated with the encoded image;

decoding the signal, to yield a decoded signal of a decoded image;

synthesizing a new texture for the decoded image based on the texture information; and

mapping the new texture onto the decoded signal of the decoded image.

9. The system of claim 8, wherein the computer-readable storage medium stores further instructions stored which, when executed by the processor, cause the processor to perform operations further comprising:

identifying a region of the encoded image having a color similar to a substitution color.

10. The system of claim 9, wherein the texture information is associated with the region.

11. The system of claim 10, wherein the computer-readable storage medium stores further instructions stored which, when executed by the processor, cause the processor to perform operations further comprising:

mapping the new texture based on the texture information into the region.

12. The system of claim 8, wherein the texture information is received in a different channel than the signal.

13. The system of claim 8, wherein the new texture has distinct dominant texture orientation.

14. The system of claim 8, wherein the computer-readable storage medium stores further instructions stored which, when executed by the processor, cause the processor to perform operations further comprising:

outputting a new signal representing the signal with the new texture mapped onto the decoded signal.

15. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:

receiving a signal indicative of an encoded image and texture information associated with the encoded image;

decoding the signal, to yield a decoded signal of a decoded image;

synthesizing a new texture for the decoded image based on the texture information; and

mapping the new texture onto the decoded signal of the decoded image.

16. The computer-readable storage device of claim 15, wherein the computer-readable storage device stores additional instructions stored which, when executed by the computing device, cause the computing device to perform operations further comprising:

identifying a region of the encoded image having a color similar to a substitution color.

17. The computer-readable storage device of claim 16, wherein the texture information is associated with the region.

18. The computer-readable storage device of claim 17, wherein the computer-readable storage device stores additional instructions stored which, when executed by the computing device, cause the computing device to perform operations further comprising:

mapping the new texture based on the texture information into the region.

19. The computer-readable storage device of claim 15, wherein the texture information is received in a different channel than the signal.

20. The computer-readable storage device of claim 15, wherein the new texture has distinct dominant texture orientation.
