一种基于积分投影与色度匹配相结合的快速人眼嘴定位算法

Fast eye and mouth location algorithm based on integral projection and color matching

设计一种基于积分投影与色度匹配相结合的快速人眼嘴定位算法。改进积分投影方法仅对选定条形人眼区域作垂直投影,利用极小值特征定位人眼,再根据人脸先验几何特征估算人嘴区域,并统计其色度分布特征。实验结果表明,该算法对于复杂背景下人眼嘴定位行之有效,且能提高人眼嘴定位的计算速度,适用于实时性要求较高的场合。

This paper proposed a method which only made vertical projection for eye region, and located eye according to min- imum. Then it evaluated mouth position by means of geometric features, thus statistics its color distribution. Experimental re- suits show the effectiveness of the algorithm, which can increase the speed of eye and mouth location algorithm, and fit to the situation with high real-time demand.
