一种快速准确的人眼定位方法

A Fast and Precise Method of Eyes Location

提出一种利用快速辐射对称变换标准地定位双眼瞳孔的新方法。首先估计眉毛的大体位置,根据眉毛定位的结果,在可能存在双眼的一定区域,利用快速辐射对称变换找到黑色的特征点,用眼珠模板对检测到的特征点进行纠偏后,根据几何特征确定双眼的候选对,再次利用眼珠模板精确定位瞳孔的位置。对ORL和SJTU IPPR数据库的实验表明,该算法可以实时的定位双眼,准确率达到90%以上。

Fast radial symmetry transform can fast detect points of interest and is the improvement of generalized symmetry transform.Firsly,the location of eyebrows is estimated.According to the location of eyebrows,in certain range that possibly includes eyes,fast radial symmetry transform is used to detect black points of interest.After rectifying a deviation and according to the geometrical features,the eyes candidates are selected and the precise location can be decided by pupil model.The experiments in ORL and SJTU-IPPR fact database show the algorithm is effective and can be used in real-time system.
