Abstract

In this paper, a novel method is proposed to detect and to track pupil of one eye using MODIFIED CIRCULAR HOUGH TRANSFORM and a pair of goggles equipped with an infra -red (IR-EMD) camera. The IR-EMD, which is used in this research, is designed and built after studying several different schemes and despite its simplicity, it has very good performance and could be thought as one the practical novelties of the project. In the proposed method for PUPIL DETECTION, circular Hough transform is used and its speed and accuracy is enhanced performing several modifications. Applying the MODIFIED CIRCULAR HOUGH TRANSFORM to the image captured with an average quality camera of the IR-EMD, which is also equipped with an IR-LED ring, the accurate position of the pupil would be detected. In addition to high speed and precision, the algorithm does not require high quality camera and is robust to the input image noise and some other environmental parameters such as rotation of the head, eye make-up and background light of the image, as well. Practical experiments on several people indicate precision and performance of the proposed algorithm. Besides, in order to confirm the performance of the algorithm for almost all possible situations, the method is applied to more than 700 eye images of the CASIA-Iris V.3 database. Results show outstanding performance of the proposed method. For instance, in presence of pepper and salt noise with 50 percent intensity, the algorithm could detect the correct position of the pupil of the database images with almost 90 percent accuracy.
