Motion-Based Foreground Segmentation

A variety of useful applications demonstrate the need for precise motion-based segmentation of image data. Video compression techniques rely heavily on accurate and efficient representation of spatio-temporal regions possessing similar motion models. In addition a variety of cinematographic effects are potentially possible with successful separation of a moving object's image from an arbitrary background. Computer vision systems often depend on the ability to distinguish or describe a moving object in an image sequence. An algorithm is designed to segment a moving foreground based on block-matching motion methods and recursive tracing of the resulting motion vectors.
