8 is the number of rows (the "Y" dimension).
m is the number of columns (the "X" dimension).
n is the number of color channels (typically 1 for grayscale or 3 for RGB true color or some other color space such as HSV or LAB). Sometimes thought of as the "Z" dimension.
So you have a multispectral image. Each color channel of that multispectral image is an 8 by m 2D image, and you have n of them (one for each wavelength range, color channel). Though in your case everything is zero, so maybe you're just initializing and pre-allocating space.
