Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A filter for removing blocking artifacts, comprising: a quantizer which quantizes a block comprising video data in pixel units so as to obtain quantized values, a filter information generator which generates filter information for the block based on the obtained quantized values; a determiner which determines filtering strength for the block based on the generated filter information of the block; and a loop filter which filters the block based on the d…
