Problems solved by technology

Therefore, additional side information within the "skip" and / or "direct" modes indicating the direction of joint coding or merging with some other blocks can lead to the introduction of unnecessary redundancy and thus rate-distortion (R-D) efficiency Loss

Abstract

Provided are methods and apparatus for context dependent merging for SKIP / DIRECT modes for video encoding and decoding. An apparatus includes an encoder (300) for joint coding partitions of an image region using frame partitioning and a partition merging procedure, wherein any given one of the partitions that use a coding mode with implicit coding rules is subject to being merged, with another oneof the partitions, using a distinct merging rule different than that used for a coding mode with explicit coding rules.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application Serial No. 60 / 911,489, filed April 12, 2007, which is hereby incorporated by reference in its entirety. technical field [0003] The present principles relate generally to video encoding and decoding, and more particularly to methods and apparatus for context-dependent incorporation of skip / direct modes of video encoding and decoding. Background technique [0004] In the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Moving Picture Experts Group-4 (MPEG-4) Part 10 Advanced Video Coding (AVC) Standard / International Telecommunication Union Telecommunication Sector (ITU-T) H.264 Recommendation (hereinafter referred to as "MPEG-4 AVC standard), "SKIP" and "DIRECT" modes are very special modes. "SKIP" and "DIRECT" modes do not include any The bits of the vector. The "skip" and "direct" modes are optimized f...
