a=imread('f:\tu.jpg');
j=imnoise(a,'salt&pepper',0.02);
subplot(2,2,1),imshow(a)
subplot(2,2,2),imshow(j)
k=medfilt2(j);
subplot(2,2,3),imshow(k)
运行结果后出现??? Error using ==> imnoise
Unknown noise type: 'salt&pepper'.

Error in ==> e:\MATLAB6p5p1\work\zuoye.m
On line 2 ==> j=imnoise(a,'salt&pepper',0.02);
怎么回事啊啊 还有就是 彩色图象怎么变成黑色的了 要怎么才能显示彩色的呀
帮帮忙 谢谢了各位

salt&pepper改为salt空格 &空格pepper就可以了
显示的那个问题可以试试在参数那里加上map看行不行
