Block-based interleaving

摘要

At least one implementation interleaves blocks from a stereo-image pair and enables intra-coding of the interleaved image using corresponding blocks as references. One particular implementation accesses a first image that includes multiple blocks, one of which is a first-image block. A second image is accessed that includes multiple blocks, one of which is a second-image block that has overlapping content with the first-image block. The multiple blocks of the first and second images are interleaved on a block basis to form an interleaved image. At least a portion of the interleaved image is encoded by encoding the first-image block using the second-image block as a reference. Another implementation provides the encoded portion in signal. Yet another implementation accesses the encoded image and decodes the portion by using the second-image block as a reference.

主权项

1. A method comprising:
accessing a first image that includes multiple blocks, the multiple blocks of the first image including a first-image block, wherein the first-image block is a macroblock; accessing a second image that includes multiple blocks, the multiple blocks of the second image including a second-image block that has overlapping content with the first-image block, wherein the first image and the second image are stereo image pairs; interleaving the multiple blocks of the first image and the multiple blocks of the second image on a block basis to form an interleaved image, the interleaved image being a composite image of the first image and the second image; encoding at least a portion of the interleaved image by encoding the first-image block using the second-image block as a reference, wherein encoding the first-image block comprises identifying the second-image block based on a value of disparity for the first-image block; and providing the encoded first-image block for transmission or storage.
