Abstract:

In order to improve the robustness of human eye positioning, accuracy and detection speed,and improve the applicability of the algorithm,a methord was proposed that combining color information based on YC_bC_r color space with gray level projection and human iris saturation information based on HIS color space. Color was extracted with Gaussian distribution model of improved algorithm base on C_b, C_r Component of Image,and detected face region through analysis of color regions.The graylevel projection methods to locate eyebrow regions was adopted,the human iris saturation information was used to locate eyes accurately. Experimental results show that the right accuracy of eye positioning is 85%, positioning time is 0.072 6 s.

Key words: eyes location, extract color, gray-level projection, iris saturation
