Title:
IMPROVED NON-LOCAL ADAPTIVE LOOP FILTER PROCESSING
Document Type and Number:
WIPO Patent Application WO/2018/224006
Kind Code:
A1
Abstract:
Aspects of the disclosure provide a method for forming patch groups. The method can include determining a list of K motion vectors (MVs) for each current patch to form a patch group that includes the respective current patch and K reference patches corresponding to the K MVs, wherein the current patches are included in a reconstructed picture. The list of K MVs of a first current patch that is one of the current patches is determined by performing a neighbor-based fast search (NBFS) process. The NBFS process can include selecting K MVs from lists of K MVs of at least one neighboring current patch of the first patch to form a first list of K MVs of the first current patch, and performing a first refinement process to obtain a second list of K MVs of the first current patch based on the first list of K MVs.
