A Haar-like features based eye detection algorithm was introduced in this paper. With its fast searching speed and high detection rate, the algorithm fits to be implemented on portable platform. TI TMS320DM6446 is a high performance digital multimedia processing chip provided by Texas Instruments Corporation. With the eye detection algorithm packed into codec, an optimized real time eye detection system was implemented on DM6446 platform. The detection algorithm codec was loaded into the DSP-side for remote call. Application on the ARM-side captured face images from camera and output detection results to computer monitor. The implemented eye detection codec was also employed in a face recognition system. Experimental results demonstrate that the real time eye detection system on DM6446 can search and locate eyes effectively with limited chip resources occupied.
