Fingerprint Recognize System

关于BP网络的设计及改进方案实现分类，包含matlab源程序(On the BP network to achieve improvement program design and classification, including source code matlab)

这个程序检测出了图像中的直线,而且用绿色标出直线,直线断电用+表示,并且用不同颜色标出了最长的直线(this procedure detected the image straight, and marked with a green line, a straight line with power outages, and with different colors marked the longest line)

由于matlab高低版本的不同，M文件的格式有的时候是.M有的时候是.m 这时候可以批次的修改为需要的的大写或者小写。(The capital letters exchange in matlab)

在8*8子图像块前提下，不同压缩比对图像压缩效果的影响(8* 8 sub-image block under the premise of different compression than the image compression)
