[Sean de Wolski]

%Median:

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

Answer 2

[Darshan A]

Thanks a lot for the quick response..!

[Darshan A]

got some error. this is working code..

Irgb = imread('pathname');

for ii=1:3

Irgb(:,:,ii) = medfilt2(Irgb(:,:,ii),[3 3]);

end

imshow(Irgb);

[Sean de Wolski]

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

[Darshan A]

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.

[Sean de Wolski]

No it's mine.

medfilt2(Irgb,[3 3]);

I was confusing it with conv2. (what you would use for mean or std)
