Univariate Images

Univariate images are m-by-n-by-1 (where m and n are pixels) array where each value in the array represents a pixel intensity value.

Univariate Array

Multivariate Image 3 Variables

Most digital photos are "Truecolor" or "RGB" (Red/Green/Blue) and come in the form or m-by-n-by-3 where there are 3 "slabs" of pixel intensities.

RBG Array

Multivariate Image 3+ Variables

Images with more than 3 variables are often referred to as hyperspectral images. These arrays will be m-by-n-by-k where k might be select wavelengths or an entire spectrum for each m/n pixel.
