摘　　要：针对跟踪系统中实时性和鲁棒性的要求,提出了一种基于肤色检测、自动筛选小区域搜寻特征点的快速跟踪方法。首先利用对彩色图像进行肤色检测,筛选出包含肤色的小区域,然后根据比例参数确定小区域的范围,计算小区域中特征点的质心与肤色检测区域中心构成反馈来实现跟踪。实验结果证明该方法可以很好地解决实时跟踪问题,并在出现肤色混淆的情况下也有相当好的鲁棒性。Aimed the requirement of real-time and robustness in track system, a new method that based on skin color detect, auto region selected for feature track is put forward. Firstly using skin color detect for color image, filter the region of skin color. And then fix the region with proportion parameter, compute the centroid of feature points in the region, feedback to the center of the region for tracking. Proved by the system proposed, experiment result meets the requirement well even if in color confuse condition.
