摘要：
This paper reports the development of a new optical flow detection method which encodes motion components in four image data samples taken by flow shooting. It detects optical flows from the image data by a simple filtering and arithmetic process. Flow shooting is accomplished by low-speed transfer in vertical CCD registers and a multiple field shifts in IT-CCD image sensors. The method provides real-time optical flow detection for simple signal processing. The effectiveness of the method has been verified in real-time shooting.
