Abstract
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 for inter-coding 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.

An apparatus for decoding video data for a picture, the video data having local brightness variation, the video decoder comprising:
- a decoder for decoding the video data using a localized weighted prediction function to determine weights for the local brightness variation,
- wherein the weights for the localized weighted prediction function are derived implicitly.
A method for decoding video data for a picture, the video data having local brightness variation, comprising the step of:
- decoding the video data using a localized weighted prediction function to determine weights for the local brightness variation,
- wherein the weights for the localized weighted prediction function are derived implicitly.
