摘要：

The location of eyes plays a significant role in the field of face recognition and facial expression recognition. An algorithm for eye location with Sobel edge extraction is presented. At first, median filter is used to preprocess the image. Then, the segmentation of eyebrows and eyes is completed by the gray integral projection. Finally, the edge of eyes is extracted with Sobel operator and the accurate position of eyes is determined. Experiments are done on JAFFE facial expressions database. The results show the effectiveness and simplicity of the proposed algorithm. Compared with circle examination of Hough transformation and traditional template matching, the method proposed has shorter time-consuming. © ICIC International 2014.
