Báo cáo hóa học: " Research Article A Novel Face Segmentation Algorithm from a Video Sequence for Real-Time Face Recognition" potx
... 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...
