| Abstract: | To confirm the pilot fatigue, most of methods are carried out through the analysis of eye states. A new algorithm of eye states recognition was proposed based on combining of radial symmetry transform and circular Hough transform. Firstly, the eye states were recognized based on radial symmetry characteristic of iris when eyes were open, and then for the images which were not recognized only by radial symmetry transform, the center and radius of iris were determined by circular Hough transform. Comparing th... |
