Review of the Key Techniques of Video Velocimetry
Jin Jin Zhou, Xiaoying Wang · Applied Mechanics and Materials · 2014
Vehicle detection based on video plays a more and more important role in the intelligent transportation system (ITSs), since it presents siginificant advantages such as simple structure, less equipment, no radiation and easier to secondary development and so on over other methods. Based on those the paper summarizes the principle of video velocity measurement and object detection, furthermore, focuses on the analysis of the main content and the latest progress of background difference, frame difference and optical flow. Finally, presents the strengths and weaknesses and the technical difficulties faced, and points out directions of future research in this area.
