scenario, we have a dataset which contains multiple images in it. we want to find number of channel of each images because in these images max are rgb images and few gray scale, and for further processing it is required to convert all gray scale images(which are 1 channel) into 3 channel gray scale image. but first we find gray-scale images in a dataset then we will able to convert them from 1 channel to 3 channel gray scale image. so for that array is required which hold all images channel numbers, so help me how can implement it.

Let I be your image.
if size(I,3) == 1
fprintf('Your image is Gray\n')
elseif size(I,3) == 3
fprintf('Your image is RGB\n')
end
