Velocital information feature for charting spatio- temporal changes in digital image sequences

摘要

This paper introduces a velocital information feature that is extracted for each frame of an image sequence. The feature is based on the optical flown in each frame. A mathematical formulation for the velocital information feature is derived. Charting the feature over a sequence provides a quality metric called velocital informa- tion content(VIC). The relationship of CIV to the spatial an dtempo- ral information content is shown VIC offers a different role from traditional transmission-based quality metrics which required two im- ages: the original input image and degraded output image to calcu- late the quality metric.
