小波包学习资料,包括多种小波包应用的MALAB算法实现( good learning materials about WPD ,including many MALAB algorithms of wavelet packet )

说明：  BMD完整代码，包括灰度图片和彩色图片的去噪、去模糊等功能，去噪效果尤为突出。(Complete code of BMD, including de-noising and de-blurring functions of gray image and color image, especially outstanding de-noising effect.)

通过阈值去噪，最关键的就是要确定最佳阈值T 的大小.如果阈值太小，可以保留更多的小波系数，但同时噪声也被保留；相反，阈值太大，可以消除更多的噪声，但重要图像特征又将被滤掉，引起偏差.目前使用的阈值分为全局阈值和局部阈值.全局阈值对各层所有的小波系数或同一层内的小波系数都是统一的；局部阈值则是根据当前系数周围的局部情况来确定合适的阈值，具有灵活性.(Threshold denoising, the most critical is to determine the optimal threshold T s size. If the threshold is too small, you can retain more of the wavelet coefficients, but the noise was retained the contrary, the threshold is too large, can be eliminatedmore noise, but the important image features in turn be filtered out, causing bias current threshold is divided into a global threshold and local threshold. global Threshold the wavelet coefficients of all the wavelet coefficients of the layers or on the same floorare unity local threshold is based on the local situation of the current coefficient around to determine the appropriate threshold, with flexibility.)

brovery图像融合代码，效果比较好，还有两幅测试图像，一幅是高分辨率的全彩色图像，另一幅是多光谱图像(brovery image fusion code, the results were better. There are two test images, a high-resolution full-color images, the other is a multi-spectral image)

CT图像重建中经典的代数重建算法，其中还有我算的A矩阵的数据(CT image reconstruction in classical algebraic reconstruction algorithm, which there I counted A data matrix)

该文件包含高斯高通滤波的源代码和高斯低通滤波的源代码，可以运行，效果很好(Gaussian high-pass filter Gaussian low-pass filtering )

此文件一共包含3个m文件。第一个文件的功能是绘制一个二值图像，并显示其傅立叶幅度谱。文件2功能是设计频域理想低通滤波器，并加以验证：读入一个二值图像(cameraman.tif)加噪声后在频域进行低通滤波观察滤波后的图像效果。文件3的功能是对图像eight.tif加入椒盐噪声后，实现Butterworth低通滤波.(This file contains 3 m documents. Functions of first file is to draw a binary image, and displays its Fourier amplitude spectrum. Document 2 is designed to function a frequency domain ideal low-pass filter , and verified it: reading a binary image (cameraman.tif) plus noise on it and smoothing it in the frequency domain using low-pass filtering.The filtered effect will be observed by displaying image.Document 3 is designed to read a binary image(eight.tif) and add salt and pepper noise on it, realized frequence domain Butterworth low-pass filter.)

snake活动轮廓边界提取源码.不错的算法哦(active contour snake boundary extraction source. Oh good algorithm)

说明：  matlab GUI 界面，全息图重建，通过改变Z和lamada可以得到-1级，0级，1级再现图(Matlab GUI interface, hologram reconstruction, by changing Z and lamada can be - 1, 0, 1 level reproduction map)
