摘要:
There are provided video encoders, video decoders, and corresponding encoding and decoding methods for video data for a picture, wherein the video data has local brightness variation. The video encoder includes an encoder (200) for intercoding the video data using a localized weighted function to determine weights for the local brightness variation. The weights for the localized weighted function are derived without explicit coding.
