LOCAL ILLUMINATION AND COLOR COMPENSATION WITHOUT EXPLICIT SIGNALING

摘要

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 an 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 method and apparatus for decoding the signal the encoded signal.
