In order to reduce the effect on the eyes location caused by the variation of illumination and expression, this paper proposes a human eye location algorithm based on the multi-scale self-quotient image and morphological filtering. Firstly, the multi-scale self-quotient image is used to offset the lighting effects on the face, then the morphological open-close operation will be taken to enhance the local features around the eyes and relevant coefficient is used to roughly position the eyes. At last, the variance projection method will be used to analyze the roughly-positioned areas and binarize them to position accurately the central point of the eye. The experiments on the images from JAFFE Database, Yale B Database and AR database have shown that the proposed algorithm can well position the center of the eye, and it is robust to deal with the changes of illumination and expressions.
