An approach for analyzing the traces of moving objects

The trace image of moving object is directly obtained from video signal and stored in one frame memory. From the trace image, one can measure the concentration, velocity, and acceleration of objects. The morphology of each trace can also be analyzed. Because only one frame of trace image is needed, it is less expensive, but more automatic, so it can be wide used in many fields. An application example of semen analysis is given.<
