彩色图像平滑

示例一：

fc=imread('003.jpg');

imshow(fc);

fR=fc(:,:,1);fG=fc(:,:,2);fB=fc(:,:,3);

w=fspecial('average',25);

fR_filtered=imfilter(fR,w);

fG_filtered=imfilter(fG,w);

fB_filtered=imfilter(fB,w);

fc_RGB=cat(3,fR_filtered,fG_filtered,fB_filtered);

figure,imshow(fc_RGB);

 

示例二：

h=rgb2hsi(fc);

H=h(:,:,1);S=h(:,:,2);I=h(:,:,3);

w=fspecial('average',25);

I_filtered=imfilter(I,w,'replicate');

h=cat(3,H,S,I_filtered);

f=hsi2rgb(h);

f=min(f,1);

imshow(f);
