Matlab image denoising

What kind of filter do you want to use? I have a program here, which uses the mean and median methods:

g = im read(' E:\ 1 . jpg ')； % Read in the specific location of the image,

V=imnoise(g,' salt & pepper', 0.1);

Subplots (2, 2,1);

Image display (g)

Subplots (2, 2, 2);

[h, w]= size (v);

n = 9；

f = double(v)；

a=ones(n，n)；

y = f；

For i= 1:h-n+ 1

For j= 1:w-n+ 1

a=f(i:i+(n- 1)，j:j+(n- 1))；

s = sum(sum(a))；

y(i+(n- 1)/2，j+(n- 1)/2)= s/(n * n)；

end

end

Subplots (2, 2, 3);

imshow(uint8(y))

x = f；

For i= 1:h-n+ 1

For j= 1:w-n+ 1

c=f(i:i+(n- 1)，j:j+(n- 1))；

e=c( 1，)；

For u=2:n

e=[e，c(u，)]；

end

Mm = median (e);

x (i+(n- 1)/2，j+(n- 1)/2)= mm；

end

end

Subplots (2, 2, 4);
