Locating ROI in Iris Using Randomized Hough Transform
Paras Gulati, Teekam Singh · River Publishers eBooks · 2022
Iris segmentation is applied to the human eye to extracting the region of interest (ROI) and is used to recognize the human uniquely and efficiently. In this, we have first detected and removed the reflection mask using adaptive thresholding; then to detect edges, the Gaussian filter of Canny edge detection is used, and then the resultant reflection and boundary mask free image is used to locate the approximate iris center using randomized Hough transform and then the polar transform is used to find ROI.
