finger-recong
指纹识别源代码。思路完全是按照文件夹中网页里介绍的方法,即提取指纹中的分叉点和端点的位置作为指纹的特征值。由于今天太忙,对图像的预处理作的很失败,程序会提取出很多伪点,而指纹轮廓也没有想出办法过滤。汗,你看看能不能参考把。
三个m文件,fd.m提取指纹中的分叉点,fd2.m提取指纹中的端点,Cpoint.m则是前两个文件运行中需要调用的掩模函数。(fingerprint identification code. Thinking is entirely in accordance with the folder on the website Lane, that the fingerprints of the bifurcation point and endpoint position as a fingerprint eigenvalues. As today are too busy, the image preprocessing for the failure, the program will extract a lot of pseudo-point, and the fingerprint profile nor find a way to filter. Khan, you can look at the information put. 3 m documents, fingerprints fd.m the bifurcation point, fd2.m fingerprints of endpoint, Cpoint.m are two documents before the operation need to call the mask function.)

LMS--filtering
信号在采集和输送过程中往往会参杂着噪声和干扰,将自适应神经网络与信号处理结合起来,采用最小均方(LSM)算法设计的线性自适应滤波器将信号中的杂波成分滤除。用matlab进行仿真,证实线性自适应滤波器具有良好的滤波功能。(Signal acquisition and delivery process often mingled with the noise and interference, the adaptive neural network combined with signal processing, with a minimum mean square (LSM) linear adaptive filter algorithm designed to signal noise filter components In addition. Using matlab simulation confirms linear adaptive filter has a good filtering.)
