摘要
针对应用于运动目标检测上的差分图像法本身内在特性引起的空洞、拖影、拉长等若干缺陷问题进行了研究。沿着从差分静态背景、差分自适应的更新背景,到帧间差分,三帧差分的脉络,分析了这些方法中空洞、拖影、拉长等现象之间的联系与演变,提出了有关解决或者改进措施,并进行了相关的实验验证。
According to the application of moving target detection, the internal defects of image difference are presented and studied. From the static background subtraction and the adaptive refresh background subtraction to the interframe difference and triple frames difference, the phenomena, such as the cavity, shadow tailing and elonggation are analyzed. Some relevant solutions and improved measures are proposed, which have proved to be effective through some experiments.
