%Median:
Irgb = your_rgb_image;
for ii = 1:3
Irgb(:,:,ii) = medfilt2(Irgb(:,:,ii),ones(3)); %3x3 median
end

Well what error? How do you possibly expect us to diagnose an error we don't know?

Error using ==> medfilt2>parse_inputs at 134
MEDFILT2(A,[M N]): Second argument must consist of two integers.
Error in ==> medfilt2 at 48
[a, mn, padopt] = parse_inputs(varargin{:});
Error in ==> median_color at 3
Irgb(:,:,ii) = medfilt2(Irgb(:,:,ii),ones(3));
I am new to MATLAB , so this might have been my mistake.

No it's mine.
medfilt2(Irgb,[3 3]);
I was confusing it with conv2. (what you would use for mean or std)
