*Error using rgb2gray>parse_inputs (line 88) RGB must be a m x n x 3 array.
Error in rgb2gray (line 35) X = parse_inputs(varargin{:});*

The error says why. Your input is not RGB. Try:
size('your input')

After you call this line
im1 = imread('D:\12.jp2');
put these lines
[rows, columns, numberOfColorChannels] = size(im1) % No semicolon
if numberOfColorChannels > 1
% Do this only if you want to convert to gray level.
im1 = rgb2gray(im1);
% Optionally, can take the green channel instead of the above line
% im1 = im1(:, :, 2);
end
What does this print out in the command window?

I tried your step and it gave me the same error. I wonder if it's the fact that my image is .tiff have something to do with it. I'm just trying a basic step of getting only black and white colors. I started to try gray but that did'nt work as well.

Joe, I don't know what you did. Post your own question separately, and attach your code and image and we'll answer it there.
