| Abstract: | An improved BP algorithm is proposed for edge detection of face images.Firstly,the samples are constructed and the weighted matrix is got by exemplifying in a short time span.Then the edge of binary images can be detected through the process.Furthermore, first divide each gray-scale image into 8 binary planes with different gray level,and then naturally the images surface up through synthe- sizing the edge of each binary plane.Applying the method to face images' edge detection,free continuous edge is acquired,the virtues of which lies in its strong resistance against noise pollution and is widely adopted in practice. |
