Although engineering is a study entrenched firmly in belief of pragmatism, I have always believed its impact need not be limited to pragmatism. Pragmatism is not the boundaries that define engineering, just the (sometimes unforgiving) rules by which we sight our goals. This book studies two major problems of content-based video processing for a media-based technology: Video Object Plane (VOP) Extraction and Representation, in support of the MPEG-4 and MPEG-7 video standards, respectively. After reviewing relevant image and video processing techniques, we introduce the concept of Voronoi Ordered Spaces for both VOP extraction and representation to integrate shape information into low-level optimization algorithms and to derive robust shape descriptors, respectively. We implement a video object segmentation system with a novel surface optimization scheme that integrates Voronoi Ordered Spaces with existing techniques to balance visual information against predictions of models of a priori information.
