An approach to face detection and recognition

Face detection has attracted immense attention because it has many applications in computer vision communication and automatic control system. Face detection is a method to detect a face from an image which have several attributes in that image. Research into face detection, expression recognition, face tracking, pose estimation is required. By giving a single image, challenge is to detect the face from that image. Face detection is a challenging task because faces are not rigid and it changes in size, shape, color etc. Face detection become more challenging task when given image is not clear and occluded by any other thing and not proper lightning, not facing camera etc. In this paper, viola Jones algorithm is used to detect face and principal component analysis for face recognition.
