28个vc++图像处理原程序之--对比度拉伸(28 vc++ Image processing of the original procedure- contrast stretching)

利用多项式纠正(一次项)进行几何纠正，纠正过程采用反解法，重采样方法采用双线性内插。(The use of polynomial corrected (one-time items) for geometric correction, correct the process of adoption of anti-solution, re-sampling method using bilinear interpolation.)

实现一个信号的WVD变换，针对的信号是非平稳的随机信号(To achieve a WVD transformation of a signal, the signal is a non-stationary random signal.)

该文档是自适应信号处理研究的一篇研究生毕业论文，介绍了自适应的几种常见算法，如LMS，NLMS等等，并在最后有相关的MATLAB程序（LMS程序 自适应滤波器，陷波器，分离器等程序）可以作为自适应信号处理初学者的参考资料(This document is an adaptive signal processing graduate thesis introduces several common adaptive algorithms, such as LMS, NLMS, etc., and the final program has an associated MATLAB (LMS process adaptive filter, notch , splitters and other procedures) can be used as a reference adaptive signal processing information for beginners)

实现图像文件（如bmp等）的读取、显示、真彩图转换成灰度图、灰度图转化为二值图及绘制图像直方图功能。(Achieve an image file (such as bmp, etc.) to read, display, true color conversion to grayscale, converted to grayscale and binary image histogram function to draw the image.)

经典ldpc编译码程序 gallager的博士论文里的部分仿真程序,(Classic LDPC decoding programming gallagher s doctoral thesis in part of the simulation program,)

用hough变换提取直线的C++代码，效果比较好，可以灵活改变可提取直线的条数，适用于提取多条直线。(line detecting using hough tranaformation)

盒状滤波器，可以用来用来对图像进行滤波，对图像的预处理(Box-shaped filter can be used for image filtering, pre-processing of the image)

自己用水平集方法编的，实现了医学图像的分割，效果不错，可试一下(Their allocation by level set method, and realize the medical image segmentation, the effect good, can try)

说明：  利用97小波变换进行图像压缩，用matlab仿真，实验证明它具有较高的压缩比(using wavelet transform image compression using Matlab simulation experiment to prove that it has a higher compression ratio)
