| Abstract(in English) | A method which applies the separability filter to facial images to extract the facial parts, whose shape is a circular form, such as the irises has been proposed. However, this filter extracts not only the irises but also the other facial parts such as nostrils. Therefore, this paper presents a method which estimates the region including the irises and extracts the irises from the obtained region by the separability filter. In the proposed method, a region including the eyes is estimated by using the features of the color of the eyes. Further, the proposed method calculates the location of the middle of the eyebrows from the output of the circle-frequency filter. According to the middle of the eyebrows, the region including the irises is estimated ; and then applying the separability filter to the obtained region, the irises can be accurately extracted. |
