我也是做类似的，跑3000fps，也看了这个sdm,想用上一帧的boudingbox来做检测。看sdm代码时，第一帧检测用的是检测器检测后变换的框，接下来的跟踪使用的是最小外接矩形，竟然检测效果很好。于是我换成全部用人脸检测器变化后的框来做检测，效果不好了。考虑到这种情况，想知道在训练时所用的boudingbox是怎么算的，用的哪种...正在读代码..

训练时的bounding box尽量在人脸检测出来的box附近随机扰动一下，也可以跟踪时使用的最小外接矩形框随机变动一下，这样对于predict时有更强的鲁棒性

请问对于嘴张大的情况，嘴唇轮廓找的怎么样呢？

你也在做这块呢？我也正在弄，做的不好，想用光流法，对于眼睛和嘴巴的形变无力。考虑到它们的形变方向在两眼连线的法线方向上，所以想修改光流法在计算其中一个运动分量时的部分，但是还没弄出来。另外我试了转换颜色空间，小波纹理都不理想..
随机扰动的效果的确好像好了些..前段时间加上了，最近木有看了..跟踪人眼人嘴这块思路不好，作者可以提个思路不..谢谢啦..
