Hi, Usually the amount of entropy is between the range [0,1]. but after run
E = entropy(I)
E is a scalar value representing the entropy of grayscale image I that E>1.i want E between [0,1]. please guide me or suggest an another function.

You can scale the output by the maximum entropy for this image
H = entropy(I);
N = numel(I);
maxH = entropy([1:N]/N);
Hscaled = H/maxH;

If it's double, the values have to be in the range [0,1], and if its unit8, the values have to be in the range [0, 255], as far as I understood.

N is number of element in matrix.i cant understand the maxH.please explain more.
