基于HPF和Hough变换的人眼精确定位

眼睛定位是人脸识别的非常重要的一个环节,常采用基于Hough变换的方法,但这种方法计算量大、运算速度慢,对存储空间需求大。提出一种人眼快速定位的新方法。首先用混合投影法检测到眼睛瞳孔的大致位置,再利用基于圆的Hough变换快速定位出人眼,实验证明此方法大大提高了人眼定位的效率。

Eye location based on Hybrid Projection Function and Hough transform

Eyes location is a very important step in face recognition.Hough transform method is usually applied in this process,but its calculation is too large,the speed is too slow and it needs abundant memory.A new method based on Hybrid Projection Function and Hough transform for detect on and recognition of human eyes is proposed.After hybrid projection,the approximate position of human eyes are detected.Then using Hough transform on the basis of circle,the exact position of human eyes are located rapidly.Experiments are made and very promising results are achieved.
