Parametric graph-based separable transforms for video coding

Abstract:

A video decoder can be configured to receive, in a syntax structure that applies to a current block, graph-related information; determine a transform matrix based on the received graph-related syntax information; perform an inverse transform based on the determined transform matrix of one or more coefficient values to generate a residual block; and reconstruct the current block of the video data based on the residual block.
