摘要：As the first step for developing the system that generates facial caricatures automatically, we developed a method of extracting the facial region and the irises. The facial region is extracted by a thresholding procedure in which the threshold is selected based on the degree of the coincidence between the outermost edges and the region boundary. Then, another type of thresholding is performed in the facial region, and the boundary of the binary image is detected. Next, using a Hough transform, a number of small circles are detected as candidates for the irises. On the basis of the geometrical relation between the left and right irises, a pair of circles are finally selected as irises. We experimented with 30 face images. The facial regions were successfully extracted for all of images and irises were successfully recognized for 29 images. It was found that the unsuccessful case could be recovered by a verification process.
