Abstract: This paper introduces a velocital information feature that is extracted for each frame of an image sequence. The feature is based on the optical flow 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 information content (VIC). The relationship of VIC to the spatial and temporal information content is shown. VIC offers a different role from traditional transmission-based... (Update)
