动背景中高速掠过点目标的双窗口捕捉算法

为解决动背景下高速掠过点目标的实时探测问题，探讨了一种新的算法：首先采用基于帧间差分向量一阶范数的目标检测算法对图象进行预处理，实现大面积背景抑制，提取可疑目标点；然后，对提取的可疑目标点采用双窗口搜索算法捕捉运动点目标。该算法简单，运算量小，易于实现。实验结果验证了算法的有效性。

Double Windows Searching Algorithm for Fast Moving Point Target Detection Under Moving Background

A new algorithm for detecting fast moving point target under moving background is proposed, double window searching algorithm. First the target detecting method based on first-order norm of frame difference vectors is used to preprocess image for extracting suspicious points. Then the dual-windows searching algorithm is used to detect point target from these suspicious points. This algorithm is simple and easy realized. The result indicates that, this method provides a new solution to detect fast moving point targets under moving background effectively.
