Images are represented by (m x n x 3) arrays. This is basically three two-dimensional arrays behind each other. The first layer is R, the second is G and the third is B. Means, if you want to get the three layers separated:
img=imread('myimage.png');
R=img(:,:,1);
G=img(:,:,2);
B=img(:,:,3);

Why a tensor? What's wrong with a 3D array like the rest of the world? What form do you even use tensors in in MATLAB? If not arrays, then what? Structures, tables, cell arrays, what????
