Abstract

There are provided methods and apparatus for fast geometric mode decision in a video encoder. An apparatus includes an encoder (100) for performing a non-exhaustive geometric mode decision using geometric model-based partitioning modes. The encoder (100) skips a testing of the geometric model-based partitioning modes based on at least one of a correlation and a dependence between the geometric model-based partitioning modes and non-geometric partitioning modes.

Description

[0001] Cross references to related applications [0002] This application claims the benefits of the U.S. Provisional Application Serial No. 60 / 911,486 filed on April 12, 2007, the entire contents of which are incorporated herein by reference. Technical field [0003] The present principles generally relate to video encoding, and more specifically, to a method and apparatus for fast geometric mode decision (fast geometric mode decision) in a video encoder. 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 Standardization Department (ITU-T) H.264 Recommendation In the book (hereinafter referred to as "MPEG-4 AVC Standard"), inter-coded 16×16 pixel macroblocks can be split into 16×8, 8×16, or 8×8 Macroblock partition (partition). A macroblock partition of 8×8 ...
