Abstract

There are provided method and apparatus for local illumination and color compensation without explicit signaling. An apparatus includes an encoder (100) for encoding a picture by enabling at least one of color compensation and illumination compensation of at least one color component of a prediction for an image block of the picture without using explicit signaling. The method comprises at least the step of enabling the encoding of a picture described above in the apparatus (325), again without use of explicit signaling. In the description of a specific embodiment, this enabling of the color compensation and the illumination compensation is based on at least one of a group of pixels and a local signal block corresponding to the picture (330). Similar descriptions are provided for a methodand apparatus for decoding the signal the encoded signal.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application Serial No. 60 / 852,530, filed October 18, 2006, which is hereby incorporated by reference in its entirety. Furthermore, this application is related to a concurrently filed US patent application (Attorney Docket No. PU060200) entitled "METHOD AND APPARATUS FOR LOCAL ILLUMINATION AND COLORCOMPENSATION WITHOUT EXPLICIT SIGNALING". technical field [0003] The present principles relate generally to video encoding and decoding, and more particularly to methods and apparatus for local illumination and color compensation without explicit signaling. Background technique [0004] Multi-view video coding (MVC) is widely recognized as a technique suitable for a wide range of applications including, for example, free-viewpoint and 3D video applications, home entertainment and surveillance. In those multi-view applications, the amount of video data involved is usuall...
