Abstract:
At present，data from tracking moving targets consumes too much memory. An improved recording algorithm is proposed that reduces memory requirements. First, initial points are obtained by using a threeframe difference algorithm. Then the Snake algorithm is used to extend the initial points to determine the object’s contour. Finally, the Hausdorff distance measurement matches contours to standard figures and the results are saved in a text file. The improved algorithm uses approximately 0.01% of the usual memory required, so it is suitable for storing data from longterm tracking.
