为了准确地划分运动目标和背景区域,提出一种自适应阈值的运动目标提取算法,对现有基于背景差的提取算法进行改进。本算法将运动目标和背景作为两个聚类,对图像中的点按像素灰度进行分类,以聚类间的方根—算术均值距离最大作为分割阈值选择的准则,使得运动目标提取算法中二值化阈值能够自动更新,从而实现对运动目标的准确完整提取。实验结果表明,该算法能够较准确快速地提取运动目标,并对环境亮度突变、背景存在微小运动等情况具有较好的鲁棒性。

Unity WebGL版，背景透明化（画布透明），显示Html网页背景。内含Demo和项目文件。unity版本2018.4.2，测试通过。

1、ListCtrl和HeaderCtrl支持共用位图底图，可以整个应用程序使用同一张完整底图图片，完美实现换肤等需要； 2、ListCtrl和HeaderCtrl支持独立位图底图，绘制背景时各自使用自己的独立底图； 3、ListCtrl和HeaderCtrl支持纯色背景色填充； 4、背景使用顺序是：共用底图→独立底图→纯背景色； 5、各种外观要素（底图、底色、字体、字色、列表头高度等）均可自定义设置； 6、HeaderCtrl中实现在当前选择列上绘制排序标志（升序或降序）； 7、ListCtrl实现排序功能（升序或降序，字符串或数字），选择某列（即按下某列表头）时，先升序排列，再次按下该列表头时，变为降序，再按，又升序，如此反复。同时，列表头中的排序标志相应变化； 8、ListCtrl实现列表项拖拽功能，可以鼠标左键拖拽任意一项到某位置后松开，从而将该项插入到该位置处。
