How can i compute AMBE?

An objective measurement is proposed to rate the performance in preserving the original brightness. It is referred to as absolute mean brightness error (AMBE) and is defined as the absolute difference between the input and the output image’s mean AMBE = E(X) − E(Y) . X and Y denotes the input and output image, respectively. Lower AMBE indicates that the brightness is better preserved.

Refrence :

Preserving brightness in histogram equalization based contrast enhancement techniques

I am implementing the paper.

now what you want to do? who your data set look like? What you have do? What error appear in doing practice?

i m too working on this paper...can you send me the implemented code in matlab????

go for eme parameter better then amba or you can try Entropy for this
