... Thus, skin colour based face segmentation provides only coarse face segmentation, and cannot be used directly for face recognition The face presented for recognition can be a full face as shown in ... the chrominance component used in analysis and research has shown that skin colour is clustered in a small region of the chrominance plane [2] Hence, the Cb Cr plane (chrominance plane) of the ... person Here, we propose a fast and efficient approach for segmenting a face suitable for recognition Segmenting a closely cropped face requires finding a rectangle on the face image with the top left...
