Design and Use of Steerable Filters PAMI1991文章的代码，含有测试图像和demo，可运行(It implements a steerable Gaussian filter. This m-file can be used to evaluate the first directional derivative of an image, using the method outlined in: W. T. Freeman and E. H. Adelson, "The Design and Use of Steerable Filters", IEEE PAMI, 1991.)

摘要 该文主要考虑利用图像噪声再生技术来提取图像细节 其思想是利用被滤除的噪声信号进行回收再利用 通过对噪声信号和初步去噪信号进行小波变换 比较它们的小波系数 当噪声信号的小波系数达到一定的阈值时 将噪声信号的小波系数保留叠加至初步去噪信号的小波系数 然后利用传统的软阈值去噪的方法来进行图像的去噪 从而达到既能够去除噪声 又能保留图像细节的目的 实验证明 该方法较传统的方法在去噪和细节保持上有改进(Abstract In this paper, consider using images to extract the noise regeneration of its ideological image detail is the use of the noise signal was filtered to recycle through the noise signal and the initial wavelet transform de-noising signal comparison of their wavelet coefficients of the wavelet signal when the noise coefficient reaches a certain threshold will be the noise signal superimposed to the wavelet coefficients to retain the initial de-noising signal wavelet coefficients and then using the traditional soft-threshold denoising approach to image denoising in order to achieve the removal of noise can not only be able to retain The purpose of image detail that the methods of the experiment a more traditional approach to denoising and detail in there to keep improving)

这是code使用说明,对大家比较有帮助，新手必备(This is the code for use)

包括语音的录制程序，加噪程序，以及标准的噪声库，还有用谱减法实现带噪语言信号的增强等程序(ncluding voice recording program, noise procedures, and standards of noise library, as well as achieve the noisy speech signal enhancement using spectral subtraction procedure)

RGB直方图，很直观的 大家可以下载 很简单(hist RGB)

空时编码的源码,包含matlab文件,学习空时编码的好资料。(Space-time coding of the source, including the matlab file, learning a good space-time coding information.)
