Abstract :
In this study, we improve the modified gradient method for face localization. In the modified gradient method (MGM) an approach similar to Roberts operator was used for detecting edges in face images. The Sobel edge detector is proposed for detecting edges of a face and generating the gradients for the face detection. Preliminary experimental results show that our proposed method can detect the face more accurately than that of the modified gradient method.
