Scalable shape encoding is an important requirement of highly scalable object-based video coding. In this paper, a new scalable vertex-based shape coding scheme is proposed that uses temporal prediction. During shape coding of a video object, the object shape in the first frame is scalable intra-coded using the method described in . For scalable shape coding of subsequent frames, temporal prediction is conducted during the coding of coarser layers. Contour matching in the curvature scaledoi:10.1109/icme.2005.1521520 dblp:conf/icmcs/HuSWK05 fatcat:mfwqjs2nk5fxvkiyjldjnbbnay
