Methods and equipment for decoding video data, an immutant storage media read by computers

Abstract

The invention relates to a method and apparatus for decoding video data and computer-readable non-volatile storage media. An exemplified apparatus for decoding video data includes memory configured to store video data and one or more processors implemented in a circuit and coupled to the memory for communication. One or more processors are configured to reshape the reference block of the mapped region by using forward mapping functions to form the reference block of the mapped region and taking local illumination compensation (LIC) model parameters from the reference block of the mapped region and the adjacent reconstructed block of the mapped region. One or more processors are configured to apply LIC model parameters to motion-compensated prediction signals and to decode video data based on the application of LIC model parameters.
