This paper implements a new method to detect a human skin and faces from colored images. The proposed system based on the detection of all pixels in colored images which are probably a human skin via a reference skin colors matrix. The image then goes through some modifications to enhance the face detection. The circularity feature was used to distinguish human faces from other objects with similar skin color. The proposed system was tested using MatLab using different real images and the simulation results show effectiveness of the proposed method.
