JCTVC-J0127 Integer Color Transforms and Resampling Filters for HEVC Applications [W. Dai, M. Krishnan, P. Topiwala (FastVDO)]

Techniques for integer color transforms and spatial resampling are described for HEVC applications, extending contributions previously presented in Torino and Geneva. Resampling filters are commonly used in a variety of image processing tasks. They are intimately related to two- and multi-channel filter banks, as well as to the well known Laplacian pyramid. They arise in video coding applications in several instances: a) spatial scalability, b) resolution adaptation, and c) color sampling, as part of 4:4:4 coding. Color transforms are another common component of 4:4:4 coding. This proposal describes an approach to the design and use of these component technologies.

The contributor proposed putting a software tool into the reference software. The contributor indicate that the software would be provided in a revision of the contribution.

For further study in AHG.
