Title:
ビデオエンコーダにおける高速な幾何学的なモードの判定方法及び装置
Document Type and Number:
Japanese Patent JP5797635
Kind Code:
B2
Abstract:
There are provided methods and apparatus for fast geometric mode decision in a video encoder. An apparatus includes an encoder for performing a non-exhaustive geometric mode decision using geometric model-based partitioning modes. The encoder 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.
