Efficient Biometric Iris Recognition Using Hough Transform With Secret Key
The demand for an accurate biometric system that provides reliable identification and verification of an individual has increased over the years. A biometric system that provides reliable and accurate identification of an individual is an iris recognition system. Iris recognition systems capture an image of an individual's eye; the iris in the image is then segmented and normalized for feature ...
متن کاملIris Segmentation Using Improved Hough Transform
This paper presents an efficient iris segmentation algorithm. It uses an improved circular Hough transform to detect the inner boundary and the integro-differential operator to detect the outer boundary of iris from a given eye image. Search space of the standard circular Hough transform is reduced from three dimensions (center coordinates and radius) to only one dimension, which is the radius....
متن کاملCircular Hough Transform for Iris localization
Th is article p resents a robust method for detecting iris features in frontal face images based on circular Hough transform. The software of the applicat ion is based on detecting the circles surrounding the exterio r iris pattern from a set of facial images in d ifferent color spaces. The circular Hough transform is used for this purpose. First an edge detection technique is used for finding ...
متن کاملCoin Recognition Using Circular Hough Transform
This paper represents algorithm for recognition of the coins of different denomination. The proposed system first uses a canny edge detection to generate an edge map, then uses CHT (Circular Hough transform) to recognize the coins and further find the radii of them. Based on the radius of the coin, the coins of different denomination are classified. The experimental result shows that the Hough ...
متن کاملIris Segmentation and Recognition Using Circular Hough Transform and Wavelet Features
Iris patterns have been proven to be unique for each individual making them useful in human identification. Segmentation and feature extraction are crucial steps in matching one iris image with another. In this paper, iris segmentation is performed using Canny edge detection and the circular Hough transform. To overcome the pupil-iris center offset as well as iris stretching due to pupil dilati...
