this paper presents the method that extracts by using watershed algorithm the area which is available for the feature factor in the iris. The inputted image is preprocessed and transferred to the texture block pattern by Polar Coordinate System Transformation. In this paper, the iris feature area is extracted from the image of Texture Block Pattern using Watershed Algorithm. The extracted area is indexed by average value and size of the feature area. After the position information of the feature area is rearranged by Polar Coordinate System Inverse-Transformation. In result, the proposed method showed that is possible to extract the definite iris feature.
