compressing the image using JPEG 2000 compression coding to get 10:1 ratio

可以打开大部分图片格式包括bmp、jpg等，并对其进行图片的基本处理包括翻转、镜像、傅里叶变换、直方图统计及均衡化、锐化、柔化、加椒盐或高斯噪声、中值滤波、Sobel边缘检测、高斯边缘检测、灰度阀值边缘检测、区域生长、旋转、缩放等操作(Can open most image formats including bmp, jpg, etc., and its basic image processing including flip, mirror, Fourier transform, histogram equalization statistics and, sharpen, soften, add salt and pepper or gaussian noise , median filtering, Sobel edge detection, Gaussian edge detection, gray level threshold edge detection, region growing, rotation, scaling and other operations)

说明：  基于互信息的配准程序，matlab版的，内部包括测试图像为CT和ＭＲ。是老外编的，不错。( Matlab Program to find mutual information for two images stored as vectors. The images must contain 8-bit (0-255) integer pixels Requires two data vectors X,Y which must be the same length and Nx1 in size. Written by B. Corner--2003, University of Nebraska-Lincoln )

说明：  WAVEPASTE将系数放在小波分解结构中。(WAVEPASTE Puts coefficients in a wavelet decomposition structure.)

本程序为基于快速双边滤波器的边缘保持算法，算法具有平移不变性，具有线性复杂度(this is a edge-preserving denoising method using fast bilateral filter)

采用半隐式方案实现变分水平集图像分割方法(Active contour without edge, image segmentation)

实验目的： 1） 图像水平集合 2） 图像加密算法 3） 边缘提取 4） 噪音图像的产生 （2）显示图像，理解图像的模型 （3）使用图像的不同格式，理解图像压缩的意义 （4）对图像做简单的操作 本次实验需要熟练使用以下几个MATLAB命令： imread, imwrite, imshow,figure (Experimental purposes: 1) the level of collection of image 2) image encryption algorithm 3) Edge 4) noise generated images (2) display images, understanding image model (3) the use of images in different formats, understanding the significance of image compression (4) image to do a simple experiment needs to operate the skilled use of the following MATLAB command: imread, imwrite, imshow, figure)

理解频域处理与空间域处理的等效关系与步骤，掌握频域相乘与空间域循环卷积之间的对等关系，理解DFT运算中补零的效果。(Understand the equivalent relationship and steps of frequency domain processing and space domain processing, understand the reciprocal relationship between frequency domain multiplication and space domain circular convolution, and understand the effect of zero padding in DFT operation.)

hausdorff距离的一种改进算法，是我自己编写的，用于提取焦点之后的图像配准(hausdorff distance of an improved algorithm, which I have written for the extraction of the focus after the image registration)

MATLAB程序；图像的小波系数提取，然后进行奇异值分解，得到图像的特征系数。(MATLAB program wavelet coefficients of the image extraction, and singular value decomposition, image feature coefficients.)
