SPIHT-based coding of the shape and texture of arbitrarily shaped visual objects
收藏 引用
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY 2006年 第10期16卷 1196-1208页
作者: Martin, Karl Lukac, Rastislav Plataniotis, Konstantinos N. Univ Toronto Edward S Rogers Sr Dept Elect & Comp Engn Multimedia Lab Toronto ON M5S 3G4 Canada
A new scheme for coding both the shape and texture of arbitrarily shaped visual objects is presented. Based on set partitioning on hierarchical trees (SPIHT), the proposed shape and Texture SPIHT (ST-SPIHT) employs a ... 详细信息

作者: Peter Kauff Klaas Schüür Heinrich-Hertz-Institute (HHI) Image Processing Department D-10587 Berlin Germany
This paper presents a fast motion estimator which can be used for real-time MPEG-4 encoding of arbitrarily shaped video objects. The approach is based on an existing algorithm which has already been applied successful... 详细信息
