this program is GOP. GOP is group of frame descriptor. this descriptor is define a group of picture based on Scalable Color Descriptor (SCD)

图像的点运算：各种直方图的实现，直方图规定化，直方图均衡化。(Image point operation: all kinds of the realization of the histogram, histogram specification, histogram equalization.)

bp_innerloop.m Inner loop of the backpropagtion learning algorithm. One hidden layer. Uses tanh as the transfer function. Uses the following global variables for input and/or output: Inputs1 - input patterns Desired - desired output patterns LearnRate - learning rate parameter Momentum - momentum parameter DerivIncr - increment to the derivative of the transfer function (Fahlman s trick typical value 0.2) Weights1 - first weight layer (updated by this routine) Weights2 - second weight layer (updated by this routine) deltaW1 - initialize to 0 before first call deltaW2 - initialize to 0 before first call TSS - total sum-squared error (set by this routine) Recurrent state

Program for Face Recognition (with example ORL Data base) used PCA. It showed all process data reduction, classification end visualisation

这是一个基于小波的数字音频程序。对于最近做毕业设计的同学有帮助。 (This is a wavelet-based digital audio programs. For students recently graduated design.)

外国NB的双馈风电系统传动链仿真，外国NB的双馈风电系统传动链仿真，(this is a excellent model（drive train of wind power system with double feed induction generator ) .)

用小波去噪，不同尺度下的阀值去噪，去噪效果的对比很不错(Using wavelet denoising, different scales of threshold denoising, contrast denoising effect is very good)

本书将通信技术处理技术用代码的形式表现出来，这样可以通过代码来加深对理论知识的理解。(This book will use communication technology processing code forms, and so can the code to deepen the understanding of theoretical knowledge.)
