Face detection using the shape of face with both color and edge
Y. Nara, Ye Yang, Y. Suematsu · 2005
The algorithm for the detection of faces in color scenery is proposed. Usually several faces are located in various styles with different size in input image. In our method the face projection is modeled as an elliptic shape. The elliptic size is adjusted to satisfy a certain condition that is derived from both features of the color and edges of the image. Then, to eliminate the nonface candidates, the elliptic candidates are checked whether the facial features such as eyes and mouth are involved in the area. It is concluded that several face candidates in a scene and the face candidates in the background of skin-like color are properly determined by our method.
