FILTERING METHOD FOR REMOVING BLOCK ARTIFACTS AND/OR RINGING NOISE AND APPARATUS THEREFOR

摘要

Provided are a filtering method and apparatus for removing blocking artifacts and ringing noise. The filtering method includes transforming video data on a block-by-block basis, and detecting the presence of an edge region in the video data by checking the distribution of values obtained by the transformation. Accordingly, it is possible to completely remove blocking artifacts and/or ringing noise by more effectively detecting the presence of an edge region in video data.

主权项

1. A method for decoding video frames, comprising:
creating filter information based on a distribution of values; determining filter characteristics based on the created filter information; and deblocking filtering based on the determined filter characteristics, wherein the creating comprises determining filtering strength for a current block based on the filtering information on the current block and at least one neighboring block of the current block, and the deblocking filtering comprises filtering the video data based on the determined filtering strength.
