Abstract

Technologies are generally described herein for extracting a representative motion flow from a video. Technologies are also generally described herein for retrieving a video utilizing the representative motion flow. The representative motion flow may be extracted utilizing a sliding window approach to generate interesting motion flows. The representative motion flow may be generated based on the interesting motion flows.
