Abstract: There is provided a method for decoding a video signal using a graph-based transform, the method comprising: receiving a template index for a target unit from the video signal, wherein the template index indicates a graph-based transform template to be applied to the target unit; deriving a graph-based transform matrix for the target unit corresponding to the template index; and decoding the target unit based on the graph-based transform matrix.

Abstract: Disclosed herein is a method of performing an adaptive video coding, comprising: determining transform subsets including a group index and linear transforms with dimensions M×M and N×N, wherein the linear transforms correspond to at least one of a null transform and predefined transforms; selecting an optimal transform subset for a transform unit from the determined transform subsets, wherein each of rows and columns of the transform unit corresponds to different linear transform; and encoding the optimal transform subset.

Abstract: Disclosed herein is a method of processing a graph-based signal using a geometric primitive, comprising: specifying the geometric primitive to be used for calculating an edge weight; obtaining a parameter for each of the geometric primitive; calculating an edge weight for each of edges within the image based on the parameter; and encoding the image based on the edge weight.
