A semantic video object is a two-dimensional region or shape that represents an entity with certain semantic meaning, as opposed to traditional video representation, which consists of a series of frames, and comprises an essential element in content-based multimedia services such as editing and manipulating image sequences, video surveillance, image and video indexing, and retrieval applications. Guo, with a US video company, and Kuo (U. of Southern California) explain video object segmentation technology, which aims to extract moving objects from the background, and therefore plays a fundamental role in object-based video coding using the MPEG-4 standard.

Semantic Video Object Segmentation for Content-Based Multimedia Applications provides a thorough review of state-of-the-art techniques as well as describing several novel ideas and algorithms for semantic object extraction from image sequences. Semantic object extraction is an essential element in content-based multimedia services, such as the newly developed MPEG4 and MPEG7 standards. An interactive system called SIVOG (Smart Interactive Video Object Generation) is presented, which converts user's semantic input into a form that can be conveniently integrated with low-level video processing. Thus, high-level semantic information and low-level video features are integrated seamlessly into a smart segmentation system. A region and temporal adaptive algorithm was further proposed to improve the efficiency of the SIVOG system so that it is feasible to achieve nearly real-time video object segmentation with robust and accurate performances. Also included is an examination of the shape coding problem and the object segmentation problem simultaneously.
Semantic Video Object Segmentation for Content-Based Multimedia Applications will be of great interest to research scientists and graduate-level students working in the area of content-based multimedia representation and applications and its related fields.
