... WORK We propose an effective algorithm for eye-wink interpreta- tion for human- machine interface. By integrating SVM and dynamic programming, the eye-wink control interpretation system will enable ... eye detec- tion and tracking research. It can be applied for vision-based human- machine interface (HMI) applications such as moni- toring human vigilance [1–6] and assisting the disable [7, 8]. The ... and then interprets the eye winking as certain commands for human- machine interface. In the experiments, our system demonstrates better performance as well as higher accuracy.
