Attached are two blockproc demos. It should be easy for you to adapt them to get the entropy according to whatever formula they gave you.

This is not what I'm looking for. anyway thank you

I know it's not exactly what you want - that's why I said you'd need to adapt them. I didn't give you a turnkey solution outright.

Well, what is your formula for visual and edge entropy? Whatever they are, I don't know why you can't use them with blockproc(). Maybe you can explain it to me.

Sorry, I can't.

One reason is that I don't have the wavelet toolbox because I never have need to use it. Unfortunately the guy who would always answer the wavelet questions, Wayne King, doesn't seem to visit this forum anymore. Good luck with it though.
