- 经实验发现，用背景减除方法也可以针对某些摄像机运动的情况，而非像大部分文章中所提到的该方法仅仅适合于摄像机静止的情况，而且效果还要较好！实验视频可以是一段足球视频！ -experiment found that the use of background subtraction method can also be targeted at certain camera movements, Most of the essays rather than as has been describe
HistogramEqualization.rar
- 本实验要求编写一个计算图像直方图的程序并要求讨论直方图均衡化技术，最后对图3.8（a）进行均衡化处理。直方图是多种空间域处理技术的基础，直方图操作能有效的用于图像增强。在实验中根据直方图对应的离散函数可以编写出计算一个图像直方图的函数，直方图均衡化则是借助于直方图灰度变换实现灰度映射从而达到图像增强的目的。实验通过得到原始图像的直方图，直方图均衡化变换函数图和增强后的图像增强后图像的直方图这些实验数据来解释图像被增强的原因。,In this study requested to prepare
