Abstract

There are provided methods and apparatus for reduced complexity template matching prediction for video encoding and decoding. The encoding method encodes at least an image block in a picture using template matching prediction (615, 620, 640, 641, 642), wherein the template matching prediction is selectably constrained using one or more constraining criterion that reduces a complexity of performing the template matching prediction (615, 625, 640).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 61 / 296,329, filed January 19, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to encoding and decoding of video, and more particularly relates to a reduced-complexity template matching prediction method and device for video encoding and decoding. Background technique [0004] Sub-pixel (sub-pel) motion compensation is widely used in current video encoders and decoders. For example, in the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC), Motion Picture Experts Group-4 (MPEG-4) Part 10, Advanced Video Coding (AVC) Standard / International Telecommunication Union, Telecommunications Sector (ITU-T) In the H.264 proposal (hereinafter abbreviated as "MPEG-4AVC standard"), motion compensation with a precision of 1 / 4 pixel ...
