基于动态椭圆滤波器的人脸定位

针对传统肤色分割算法无法将人脸从类似肤色的背景分割出来这一个问题,提出一种基于动态椭圆滤波器的人脸定位算法.该算法利用积分投影法预测人脸可能的范围和位置,并结合椭圆的紧密度概念调整滤波器参数,构造最优滤波器,把肤色分割后的连通区域中非人脸的类肤色区域过滤掉,有效地减少类肤色区域带来的干扰,再结合模板匹配方法对人脸进行定位.

Face Location Based on Dynamic Ellipse Filters

Aiming at the problem that traditional skin-segment algorithm could not efficiently divide a face from its background whose color was similar to that of the face,a reliable face location algorithm based on dynamic ellipse filters,was presented.A possible position and the size of a face were predicted through integration projection.In combination with Density of the ellipse,the filter would be adjusted to make itself best so that it could remove the region that was connected to the face effectively.
