METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL BY USING SEPARABLE GRAPH-BASED TRANSFORM |
摘要 |
The present invention provides a method for decoding a video signal by using a graph-based transform, comprising the steps of: parsing a transform index from the video signal; generating a line graph on the basis of edge information on a target unit; aligning transform vectors for each of segments of the line graph on the basis of a transform type corresponding to the transform index; acquiring a transform kernel by realigning the transform vectors for each of segments of the line graph according to a predetermined condition; and performing an inverse transform on the target unit on the basis of the transform kernel. |
