Title:
MODELING METHOD AND SYSTEM BASED ON CONTEXT IN TRANSFORM DOMAIN OF IMAGE/VIDEO
Document Type and Number:
WIPO Patent Application WO/2012/149904
Kind Code:
A1
Abstract:
A modeling method and system based on the context in the transform domain of an image/video in the image/video coding/decoding and other processing technical fields. Compression or other processing can be performed on dynamic or static images by approximating a natural image to a two-dimensional Markov random field which has radial and reverse radial relevance simultaneously in the DCT transform domain or another transform domain and depicting the direction relevance of an image signal in a two-dimensional change domain using the model.
