  • Image decontouring in high dynamic range video processing
    Patent number: 9911179
    Abstract: A set of optimized operational parameter values is generated for performing decontouring operations on a predicted image. The predicted image is predicted from a first image mapped from a second image that has a higher dynamic range than the first image. Based on the set of optimized operational parameter values, smoothen operations and selection/masking based on a residual mask are performed on the predicted image. The set of optimized operational parameter values is encoded into a part of a multi-layer video signal that includes the first image, and can be used by a recipient decoder to generate a decontoured image based on the predicted image and reconstruct a version of the second image.
