Adaptive geometric partitioning for video decoding

Abstract

There are provided methods and apparatus for adaptive geometric partitioning for video encoding and decoding. An apparatus includes an encoder (900) for encoding image data corresponding to pictures by adaptively partitioning at least portions of the pictures responsive to at least one parametric model. The at least one parametric model involves at least one of implicit and explicit formulation of at least one curve.

Description

[0001] Cross reference to related applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 834,993, filed August 2, 2006, which is hereby incorporated by reference in its entirety. In addition, this application is related to a commonly assigned non-provisional patent application entitled "METHODS ANDAPPARATUS FOR ADAPTIVE GEOMETRIC PARTITIONING FOR VIDEOENCODING" with Attorney Docket No. PU060147, filed at This is incorporated by reference and filed herewith. technical field [0003] The present principles relate generally to video encoding and decoding, and more particularly to adaptive geometric partitioning methods and apparatus for video encoding and decoding. Background technique [0004] Most video coding techniques utilize prediction plus residual coding to simulate video images. Other methods may also take prediction into account as a step in some processing of the signal transformation, such as when using a lifting...

AI Technical Summary

Problems solved by technology

The disadvantages of the fifth prior art method are inherited from the second, third and fourth prior art methods, so all those disadvantages set forth in the previous paragraphs also apply to the fifth prior art method

Therefore, such statistics cannot be used for encoding

[0020] In the fourth drawback with respect to the sixth prior art method, different video compression qualities have different accuracy requirements of geometric information in order to achieve the best compromise between distortion and coding cost

Sixth prior art method does not modify the information sent for encoding the block by block according to the video compression quality

Also, because the sixth prior art method does not, and / or instead, describe an appropriate representation of block geometry information, the sixth prior art method does not support (if needed) the accuracy of one geometry information for another A geometric information is encoded

[0021] In a fifth drawback with respect to the sixth prior art method, the sixth prior art method does not appear to be able to handle pixels that lie on a tile boundary and are partly on one side of the boundary and partly on the other side of the boundary
