Title:
METHOD AND APPARATUS OF NON-LOCAL ADAPTIVE IN-LOOP FILTERS IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2017/133660
Kind Code:
A1
Abstract:
A method and apparatus of video coding using Non-Local (NL) denoising filter are disclosed. According to the present invention, the decoded picture or the processed-decoded picture is divided into multiple blocks. The NL loop-filter is applied to a target block with NL on/off control to generate a filtered output. The NL loop-filter process comprises determining, for the target block, a patch group consisting of K nearest reference blocks within a search window located in one or more reference regions and deriving one filtered output which could be one block for the target block or one filtered patch group based on pixel values of the target block and pixel values of the patch group. The filtered output is provided for further loop-filter processing if there is any further loop-filter processing or the filtered output is provided for storing in a reference picture buffer if there is no further loop-filter processing.
