Abstract: For interference problems of the glasses in human eyes location, this paper fully exploits the eye structure information, combined with a fixed feature of glasses, proposes a new method for precise location of the human eyes. It obtains eyes regions by using AdaBoost detection algorithm. And on the basis of this, firstly, this paper divides the eye-eyebrow bar regions using gray projection function in the eyes rectangular regions. Secondly, it achieves binary processing of the eye-eyebrow bar regions by using adaptive binary circle fitting. Finally, it determines the exact position of the human eyes through the binary image circle fitting center. This method takes full advantage of the class structure of the eye round, and effectively avoids the impact of the glasses in the human eyes location. The experimental results show that the algorithm has good positioning results in the case of with and without glasses.
