Question

谁能帮我解释一下myfilt1=[1 1 1;1 1 1;1 1 1];myfilt1=myfilt1/9;filtered1=filter2(myfilt1,noisy);
低通滤波器图像增强[I,map]=imread('eight.tif');noisy=imnoise(I,'gaussian',0.05);imshow(noisy,map);myfilt1=[1 1 1;1 1 1;1 1 1];myfilt1=myfilt1/9;filtered1=filter2(myfilt1,noisy);figure;imshow(filtered1,map);myfilt2=[1 1 1;1 2 1;1 1 1];myfilt2=myfilt2/10;filtered2=filter2(myfilt2,noisy);figure;imshow(filtered2,map);myfilt3=[1 2 1;2 4 2; 1 2 1];myfilt3=filter2(myfilt3,noisy);figure;imshow(filtered3,map);

Answer 1

首先是读eight.tif图像,noise是添加了高斯噪声 imshow显示添加噪声后的图像
后面的myfilt1=[1 1 1;1 1 1;1 1 1];为邻域平均模板 myfilt1=myfilt1/9为模板归一化
