摘要
分析了在图像序列中图像局部灰值区域为二次型条件下用最大似然比方法进行运动检测的基本原理及其在一定置信度下的阈值选取问题 ,导出了一套检测数学模型 ,使得变化检测理论进一步完善。
The motion detection theory using the method of maximum likelihood ratio and the problem of threshold selection according to some confidence with the local grey value being square in image sequences is described.A series of mathematic models is deduced to enrich the change detection theory.
