Eye pupil image segmentation conducted with intensity adjustment method and active contour method

The segmentation of the eye pupil is still a trendy research topic in the field of iris recognition, because the low accuracy of this step will damage or reduce the efficiency of the iris recognition system. Therefore, it is necessary to emphasize research in the segmentation process to show accurate and appropriate results. This depends on the results of the accuracy shown from the detection of the center of the pupil of the eye. The aim of this research is to design a system that can segment the pupil area to support the application of the iris recognition system using the median filtering method at the pre-processing stage to improve image quality and remove noise in the image for accuracy and support segmentation results using the active contour method. This experiment was carried out using iris images and the results showed that the proposed method was able to segment pupil images with a high level of accuracy.
