Because the required scanning range is cut down to a large extent by use of edge detection methods, the efficiency of the minimum-discontinuity phase unwrapping algorithm is significantly improved.

由于利用边缘检测使增长环搜寻所需的扫描范围在很大程度上缩小，最小不连续相位展开算法的效率得到了很大提高。

Methods We put forward trailing algorithm through analyzing the feature for the handwriting number, combining the concept of edge element, scanning and trailing handwriting trace.

方法通过对手写体数码的特征分析，结合边沿元的概念，对书写轨迹进行扫描跟踪，提出跟踪算法。
