function M = MI_GG(X,Y)
Computes the mutual information between two quantized images: X and Y.

For Citation: M. Ceccarelli, M. di Bisceglie, C. Galdi, G. Giangregorio, S.L. Ullo, “Image Registration Using Non–Linear Diffusion”, IGARSS 2008.

NOTE: Available memory affects computational efficiency. Very good efficiency is obtained with 8-bit images quantization and 3GB RAM.

INPUT:

X --> first image

Y --> second image (same size of X)

OUTPUT:
M --> mutual information between X and Y
