I am having confusion in understanding compareHist() Method ,Can't seem to understand whats the meaning of return value by each different method. They all return different value. All i want to know if both histogram are matched then the value should be 1.0 if does not match then it should be 0.0 meaning picture matches perfectly.
Can someone explain me in Scale wise the meaning of each result value of each methods
