... of 136 ì 82 pixels, the system needs 1 131 0 clocks, for a total time of 136 à s. This result shows that the proposed design, and its hardware implementation, of an eye state recognition system ... to implement a real time such as driver drowsiness system. The proposed algorithm is implemented on an FPGA platform. In this implementation, the XC3SD3400A FPGA of Spartan 3- A DSP family, ... monitor and detect the driver’s drowsiness online and activate an alarm system immediately. In recent years, many researches on these systems have been done and their results are reported [3 12]....
