Abstract:
A method for decoding a video signal using a graph-based transform, the method being characterized by including the steps of: parsing a transform index from the video signal; obtaining context information for a target unit, where the context information includes a prediction mode for a current block or peripheral blocks; obtaining an inverse-transform kernel on the basis of at least one of the transform index and the context information; and performing an inverse transform for the current block using the inverse transform kernel.

Claim (Index 1):
A method for encoding a video signal using a graph-based transform, comprising steps of:\n checking context information for a current block, wherein the context information comprises a prediction mode for the current block or a neighboring block; calculating an edge weight between pixels within the current block using a prediction direction angle corresponding to the prediction mode for the current block or the neighboring block; deriving a transform kernel from a line graph generated based on the edge weight; and performing transform for the current block using the transform kernel.
