Abstract:This paper first analyzed the shortages for some eye location algorithms to changes in illumination,proposed a method for human eye location based on the anisotropic filtering.To eliminate the effects of light,made use of the anisotropic low-pass filter to get the input image filtered,and used open and close operator of the multi-structure morphology to highlight the feature of the eye region.Then,got the rough position of the eye by the correlation coefficient method.Finally,corrected eye position by the accurate algorithm.The algorithm to changes in illumination is not sensitive and get higher positioning accuracy in experimental. ......
