Abstract
Efficient coding of arbitrarily shaped visual objects is a new functionality of MPEG-4 visual coding standard, compared with MPEG-1 and MPEG-2. This functionality enables content-based interactivity required in many multimedia applications. There are two aspects of coding an arbitrarily shaped visual object. One is to code the shape information of the visual object (shape coding) and the other is to code the pixels in the visual object (arbitrary shape texture coding). Shape adaptive wavelet coding is a technique for efficiently coding the texture information of arbitrarily shaped visual objects. This paper presents this technique as it is used in MPEG-4
