Eye Contour Extraction Method from Monocular Image with Monkey Face

This paper proposes one method for the extraction of eye contour from monocular image with monkey face. Face region is segmented using the facial skin color model constructed from some samples and the operations of mathematical morphology. Then the face region is size normalized, and rotation normalized based on the located eyes. Taking the boundary of eye as initial point set, ACM is adopted to search for the smooth and continuous eye contour. The method can be used for facial expression recognition and emotion deduction, which is very helpful for medical science research, e.g. the traditional Chinese medicine, with monkey as experimental object.
