二维直方图，MATLAB开发，用于描述图像的二维直方图 (2D hist)

说明：  计算香浓信息熵，方便快捷的matlab代码，可以简单直接调用(Calculated Shannon information entropy, convenient matlab code can be simple and direct calls)

Content based Image retrieval

说明：  matlab语言编写的实现iris数据的最小错误贝叶斯分类(Iris data to achieve the minimum error Bayesian classification)

西北工业大学研究生课程，数字信号第五次上机作业。(Northwestern Polytechnical University post-graduate courses, digital signal Fifth-on job.)

butterworth filter for images

闪烁的灯，根据自己的设置可以设置等的闪烁方向，前后以及跳跃等等(Flashing lights, according to their own settings such as the flash can be set direction and jumping around, etc.)

说明：  This is on the power spectrum of the Matlab simulation program #use ARMA, AR, MA model and cycle map for parameter estimation system

matlab仿真的，功能是实现相关峰值的提取。能够在低信噪比下得到效果较好的相关峰(matlab simulation, feature extraction is to achieve correlation peak. Able to get better low SNR correlation peak)

This is the error backpropagation algorithm based character recognition program developed in matlab. The program folder contains the training images of some english alphabets & numerals. & trains the neural network using train command in matlab. The neural network is initialized using newff command. After the simulation, the program recognizes the input character. Accuracy on the provided images is 100 .
