im=imread("e:301clip301.tif"); im=rgb2gray(im);              im=double(im); im = imresize( im, 0.5 );    % 为了减少程序运行时间，将图像变小为原来大小的1/2 figure(1);imshow(uint8(im)); [nrow,ncol]=size(im); J= gauss( im,3,2 );          % 为了计算函数g，先对图像作guassian预平滑 %%- 计算图像梯度模值 J_x = (J(:,[2:ncol ncol])-J(:,[1 1:ncol-1]))/2; J_y = (J([2:nrow nrow],:)-J([1 1:nrow-1],:))/2;       请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

数值积--- 复合求积公式对积分问题的求解功能 用复合梯形求积公式和复合抛物线公式，对给定的积分问题进行计算。-plot--- composite numerical quadrature formula to solve the problem of integration functions for composite trapezoidal plot formula and compound parabolic formula, the right to issue integral calculation.

这是用于图像去噪方法的代码。在这里我使用高斯滤波图像去噪。在一些医学图像应用程序中，去噪后的图像是非常重要的。
