Infrared Eye-gaze Tracking System Research And Design

Eye-Gaze tracking system has become an increasingly important application domain of real-time image processing. This dissertation achieves the localization of the tracking target by detecting the movements of the user's iris which reflects the location of the target when the human concentrates his eyes onto the moving target on the computer screen. The principle and architecture of the infrared eye-gaze tracking system are introduced in detail respectively in this dissertation. We detect the precise location of the target based on the shift between the center of iris and eye corner, by employing image processing technologies etc. Based on the simulations of the tracking system on personal computer, we designed an infrared eye-gaze tracking embedded system based on the platform of Digital Signal Processing (Abbr. DSP) and Field-Programmable Gate Array (Abbr. FPGA). Specially, the main work of this dissertation includes localizing the center of iris, localizing the eye...
