Abstract

Methods and apparatus are provided for collaborative partition coding for region based filters. An apparatus includes a video encoder (100) for encoding image data for a plurality of regions in a picture. The video encoder (100) includes multiple filters for filtering the image data based on region partition information for the plurality of regions. The region partition information for the plurality of regions is shared between the multiple filters.

Description

[0001] This application is a divisional application of a patent application with a filing date of July 07, 2010, a Chinese patent application number of 201080038779.6, and an invention title of "Method and device for applying cooperative partition coding to region-based filters". technical field [0002] The principles of the present invention generally relate to video encoding and decoding, and more particularly to methods and devices for applying collaborative partition coding to region-based filters. Background technique [0003] In recent years, region-based in-loop and out-of-loop filters such as interpolation filters, deblocking / de-artifacting filters, pre / postprocessing filters, loop filters, etc., are appearing in video coding, To improve coding efficiency and perceived quality. Such filters typically partition video frames into regions based on content or rate-distortion (RD) cost. The filter structure and / or parameters can then be adapted to the local content char...
