purpose : to determine the distribution of iris colors in the population of tehran and to assess possible associations between iris color and ocular disorder methods : through a stratified random cluster sampling approach, 160 clusters were selected in different municipality districts of tehran, and the approached households were invited to a clinic. after the initial interview, all participant...

We present an automatic iris color classification method suitable for predicting human eye color. The proposed method combines the abilities of intra-palette merging clustering technique with a thorough measurement of the iris color using the MartinSchultz scale. Intra-palette merging ensures the minimum set of group colors suitable for correctly representing the color information within human ...

AIM To elucidate the associations of iris color with major eye diseases. METHODS A systematic search on Medline with coverage up to August 2013 was conducted. Assessment of the quality of studies based on their levels of evidence was in accordance with the Centre for Evidence-Based Medicine, Oxford, United Kingdom. RESULTS A relationship between darker iris color and an increased risk of ag...

Iris authentication is a popular method where persons are accurately authenticated. During authentication phase the features are extracted which are unique. Iris authentication uses IR images for authentication. This proposed work uses color iris images for authentication. Experiments are performed using ten different color models. This paper is focused on performance evaluation of color models...

Color Space Analysis for Iris Recognition by Matthew K. Monaco Master of Science in Electrical Engineering West Virginia University Arun A. Ross, Ph.D., Chair This thesis investigates issues related to the processing of multispectral and color infrared images of the iris. When utilizing the color bands of the electromagnetic spectrum, the eye color and the components of texture (luminosity and ...

This paper proposes performance evaluation of different distance measures used in color iris authentication. The color iris segmentation is carried out using histogram and circular Hough transform. The color iris features are extracted using histogram method. Different distance measures are used for iris authentication. The experimental evaluation shows that Euclidean and Manhattan distance are...

This paper presents a fast precise unsupervised iris defects detection method based on the underlying multispectral spatial probabilistic iris textural model and adaptive thresholding applied to demanding high resolution mobile device measurements. The accurate detection of iris eyelids and reflections is the prerequisite for the accurate iris recognition, both in near-infrared or visible spect...
