一个老外开发的地质统计学matlab工具箱,具有较全的统计算法如克里金(A foreigner and development of geostatistics matlab toolbox, has the full statistical algorithms such as kriging)

视频分割的matlab 程序,是用matlab开发的一个视频分割程序(Matlab video segmentation procedures are developed using matlab a video segmentation process)

从人流统计的实际工程出发,实现了基于计算机视觉的人体运动检测及跟踪系统,采用“差影法”滤掉静止帧,使用自适应的一阶递归滤波及帧差法提取运动区域,并通过数学形态滤波的开运算和闭运算改善运动区域提取效果。实验结果证明本运动跟踪方案处理简单高效 、抗噪能力强,可以完成复杂背景下运动目标的实时性检测与跟踪。(Flow statistics from the actual project, the realization of computer vision-based human motion detection and tracking system, using )
