kinect 学习笔记二（深度图像的利用--抠取用户躯体）

今天主要把深度数据和骨骼还有视频数据同步起来。算是上一次的三个的组合吧。期间遇到点易做图的问题整治了一下午：带ID的数据的ID是否准确。而且差点把自己的质疑给发到博客上来，竟然是自己代码的错误。伤心伤心。。。

直接把代码贴出来吧，也许有人觉得贴代码没水平，嗨，给自己留个小版本说不定以后还用得着，而且自信自己代码写的还算是规范，方便后来人嘛。再有一点，那个getTheContour函数画蛇添足了，实际直接利用深度数据的ID就可以抠出任务的区域。

先上实验结果：这是实时图像

然后是深度图像、骨骼图像和抠出的人体区域

这是代码，希望可以帮助到大家，当然，如果有错误欢迎指正：
