Title:
METHOD AND APPARATUS FOR VIDEO ENCODING/DECODING OF ENCODING/DECODING BLOCK FILTER INFORMATION ON THE BASIS OF A QUADTREE
Document Type and Number:
WIPO Patent Application WO/2012/057518
Kind Code:
A3
Abstract:
Disclosed are a method and apparatus for video encoding/decoding of encoding/decoding block filter information based on a quadtree. The video encoding/decoding apparatus according to one embodiment of the present invention comprises: a video encoder which segments a predicted reference video using optimum filters for each block into blocks by a layer of at least one stage, sets a segmentation flag for determining whether or not the segmented blocks are capable of being segmented again and a filter type for determining which filters are used for interpolating the blocks, and encodes the segmentation flag and the filter type into a quadtree; and a video decoder which reads the segmentation flag and the filter type from the bit stream encoded into the quadtree to restore the segmentation flag and the filter type, generates segmented blocks on the basis of the segmentation flag, and interpolates the generated blocks on the basis of the filter type to restore the reference video for optimum motion compensation.
