Suitability of Genetic Algorithm and Particle Swarm Optimization for Eye Tracking System
J. Amudha, K R Chandrika · 2016
Evolutionary algorithms provide solutions to optimization problem and its suitability to eye tracking is explored in this paper. In this paper, we compare the evolutionary methods Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) using deformable template matching for eye tracking. Here we address the various eye tracking challenges like head movements, eye movements, eye blinking and zooming that affect the efficiency of the system. GA and PSO based Eye tracking systems are presented for real time video sequence. Eye detection is done by Haar-like features. For eye tracking, GAET and PSOET use deformable template matching to find the best solution. The experimental results show that PSOET achieves tracking accuracy of 98% in less time. GAET predicted eye has high correlation to actual eye but the tracking accuracy is only 91 %.
