A real time algorithm for detection of spectacles leading to eye detection

Eye detection plays an important role in many Intelligent Human Computer Interaction (IHCI) applications such as eye tracking, eye gaze tracking, drowsiness monitoring etc. However the presence of spectacles makes the eye detection task difficult because of the glint produced by the lens. Earlier approaches on detection of eyes occluded with spectacles have been reported in literature, however with limited accuracies. This paper proposes a real-time algorithm for detection of spectacles leading to the detection of eyes. A video database of human subjects with and without spectacles has been created to evaluate the performance of the algorithm.
