Abstract In this chapter we propose a method to assess driver drowsiness based on face and eye-status analysis. The chapter starts with a detailed discussion on effective ways to create a strong classifier (the “training phase”), and it continues with a novel optimization method for the “application phase” of the classifier. Both together significantly improve the performance of our Haar-like based detectors in terms of speed, detection rate, and detection accuracy under non-ideal lighting conditions and for noisy images. The proposed framework includes a preprocessing denoising method, introduction of Global Haar-like features, a fast adaptation method to cope with rapid lighting variations, as well as an implementation of a Kalman filter tracker to reduce the search region and to indirectly support our eye-state monitoring system. Experimental results obtained for the MIT-CMU dataset, Yale dataset, and our recorded videos and comparisons with standard Haar-like detectors show noticeable improvements compared to previous methods.
