图像的熵

256色显示文件。在DOS环境下用256原色显示BMP格式的图片。(256-color display documents. In the DOS environment display with 256 color BMP format picture.)

个人写的2dpca算法，希望对大家有用。如有问题，希望联系fnger@163.com(Personal written 2dpca algorithm, useful for all of us hope. If you have any questions, wish to contact fnger@163.com)

利用SVM模型来完成对交通标志进行检测和识别(The SVM model is used to detect and identify traffic signs.)

基于MATLAB的图像二维熵的计算，采用了改进的均值滤波器模板，使结果与物理意义更加契合。(This program calculates the 2-dim entropy of images, which is based on MATLAB. It uses a better average filter template, and makes the result in accordance with the identification of entropy.)

说明：  内容：基于MATLAB的小波变换程序 具体功能：实现四级信号的小波分解和重构(Content: wavelet transform based on Matlab: four level signial wavelet decomposition and reconstruction are implemented.)

连续小波变换寻找脊线，用在信号处理、图像处理等方面（MATLAB）(Continuous wavelet transform for ridge line（MATLAB）)

通过与导航星库中的参考星进行三角形匹配实现姿态确定(satellite attitude determination)

RGB颜色转换源码程序，根据RDB颜色组成结构，使用位运算实现RGB颜色转换。(RGB color conversion source program, according to RDB color composition structure, using bit operations to achieve the RGB color conversion.)

很好用的svm工具箱，dagsvm对于图像分类效果非常好，分类精度很高，代码清洗简单。(Good use of SVM Toolbox, dagsvm for image classification effect is very good, very high classification accuracy, code cleaning easy.)

这个程序实现的是任意一个输入波长转化它的RGB分量，是由著名的色度图上转化而来(This program is to achieve an arbitrary wavelength of an input into its RGB components is determined by well-known color chart conversion from)
