Abstract
This paper presents an algorithm to detect the eyes and mouth of the faces under various imaging conditions such as with different poses, dimensions, illuminations, resolutions, wearing glasses or not and having different expressions is proposed. Initially, the algorithm converted the face region detected by the Viola-Jones algorithm into gray-scale and reduced the resolution by decimation to achieve low resolution region. The pixels that are darker than their surroundings are later located by 8 individual filters. Finally, the center of eyes and mouth are searched using a triangle model. Experiment show that, the algorithm produced 98.7% accuracy in detecting the eyes and mouth.
