Abstract

This paper describes the design of a hardware based system to locate and measure the pupil size using FPGA. The system was implemented in a Cyclone 4E EP4CE115F29C7, from Altera. The component has 114,480 logic elements, although only 8% of the component was used. To detect the pupil the system uses the Greedy Snakes Algorithm at 50 MHz input clock. The system was tested on a video with 30 fps, however, it is possible to process videos in real-time up to 60 fps.
