Face detection from a long database of face images with different backgrounds is not an easy task. In this paper, the authors demonstrate the face detection system of colored face images which is invariant to the background and acceptable illumination conditions. A threshold level is set to reject the non-human face images and the unknown human face images which are not present in the input database of face images. In this paper, the global features extraction is completed using PCA based eigen-face computation method and the detection part is completed using multi-layered feed forward Artificial Neural Networks with back propagation process.
