Use this:
[rows, columns, numberOfColorChannels] = size(I);
F = reshape(I, rows*columns, numberOfColorChannels);

hello Bhanveet,
Did you find out the solution of this error? because I am also getting the same error and I am also working on watermarking.

The image array called "message" is most likely color. Use rgb2gray() to cast it to gray scale.

What is the size of I both before and after calling imresize on the second image? Is one of the images grayscale or black and white? If so, it is possible the third dimension of the image is 1 instead of 3.
