Abstract
A method includes receiving an image frame comprising pixels, wherein each pixel comprises n color channels, generating, by a separate color channel quantization branch for each of the n color channels configured to guarantee a non-negative reconstruction error, a first sample set of quantized indices based on color values of residues for a first particular pixel in the image frame, wherein the first sample set corresponds to a first n-tuple, and generating, by an entropy encoder, an entropy encoding for the first particular pixel based on data that maps indices to n-tuples of quantized indices, wherein the first n-tuple is mapped to a first index.
