一种面向中医目诊的虹膜定位算法
An Iris Localization Algorithm for TCM Eyes Diagnosis
摘要
Abstract
The iris localization has an important supplement function for eyes diagnosis of traditional Chinese medicine. The correlation of iris and its image characters with the factors such as disease, constitution, elements of traditional Chi-nese medicine syndrome differentiation, should be thoroughly studied. In this paper, an iris localization algorithm for TCM eyes diagnosis is proposed. The approximate position of the pupil center is obtained by gray level threshold estimation, and then the Hough transform is improved via parameter tuple merging to localize the inner boundary of the iris. Then, the K-means clustering is used to estimate the approximate range of the iris region, and the initial contour is constructed. Finally, The active contour model is used to obtain the outer boundary of the iris, which avoids the failure of Hough transform in lo-calizing iris with serious image distortion.关键词
