小波程序
- 这是一个关于小波应用工程程序的期末作业，里面包括连续小波变换和离散小波变换，适合初学者使用-This is a project on the application of wavelet end of the operating procedures, including inside the continuous wavelet transform and discrete wavelet transform, for beginners
vcFFT
- 这是本人写的用vc6.0调用matlab6.5的一个程序（使用matlab引擎），实现用FFT分析复谐波信号频谱,并调用matlab来显示最终的频谱。希望对各位有点帮助。也欢迎各位提意见。 matlab位于c:\\matlab6p5 操作系统是：windows2000 -I write this is the call matlab6.5 vc6.0 with a procedure (using Matla b engine) to achieve using FFT an

wavelet_transformation
- 简单的小波压缩变换工作的原理如下: 信号和求导信号,形成的求同信号序列和求导信号序列的长度均为输入信号的长度的一半.如果输入信号序列是A={a(1),...,a(n)}求同信号S={s(1),...,s(n/2)}和求异信号D={d(1),...,d(n/2)}的计算方式为: for i=1,...,n/2 s(i)=a(2*i-1)+a(2*i) d(i)=a(2*i-1)-a(2*i) 例如输入信号是: 5,2,3,2,5,7,9,6

Iris-feature-extraction-algorithm
- 基于二维小波变换和方向向量，提出一种新的虹膜特征提取方法。该方法的基本思想是考虑虹膜纹理的 灰度变化，对于多层小波分解后的低频分量，分别求其在4个方向上的方向向量，最后形成虹膜码。测试结果表明，该方法能 有效地提高虹膜的识别率，且算法简单、快速。 -The basic principle of the method is as follows.In view of iris textural intensity variation,for the low- frequency c
