Pupil Center Location Based on Skin Color Segmentation and Radial Symmetry Transform

Le résumé fourni par la source

To realize the eye pupil center location in color face image, a new algorithm based on skin color segmentation and radial symmetry transform is proposed.The algorithm makes full use of the pupil and the surrounding region's gradient variation characteristics and radial symmetry characteristic, which can effectively solve the interference factors such as uneven spot, frame.Step: First, use the skin color model to detect the face region, and then remove the small block of the background with similar skin color by morphological opening operation and area comparison filtering method.Then, use the horizontal integral projection to determine the candidate eye regions.Finally, apply the radial symmetry transform to the candidate eye region to locate pupil center.Experimental results show that the proposed algorithm has good localization effect, and has strong robustness to various disturbances.
