In this paper, we address the problem of the efficient encoding of object boundaries. This problem is becoming increasingly important in applications such as content-based storage and retrieval, studio and television postproduction, and mobile multimedia applications. The MPEG-4 visual standard will allow the transmission of arbitrarily shaped video(More)
A major problem in object-oriented video coding is the e$cient encoding of the shape information of arbitrarily shaped objects. E$cient shape coding schemes are also needed in encoding the shape information of video object (VO) in the upcoming MPEG-4 standard. Furthermore, there are many applications where only the shape needs to be encoded, such as CAD, 3D(More)
A major problem in object oriented video coding is the eecient encoding of object boundaries. In this paper, we present a eecient method for the lossy encoding of object boundaries which are given as 8-connect chain codes. We approximate the boundary by a second order B-spline curve and consider the problem of nding the curve with the lowest bit rate for a(More)
