N1 = N2 = 4
xi = ith pixel of 4 x 4 block
What does the 'L - shaped bracket' mean? How to write code for alpha and beta?

Just consider them as regular, normal brackets, or ignore them entirely.
xBar = mean(x(:));
alpha = mean(x(x >= xBar)); % Mean of x where x >= xBar
beta = mean(x(x < xBar)); % Mean of x where x < xBar

t is the number of elements in the block, which is 16 for a 4x4 block, or the number of pixels in the image if you're doing it over the whole image. Like I said, since it's only 4x4 I think it's a sliding window and you'd just use the code I gave you in the other answer and not even use t.
