I am using the normalize function with this params:
normalize(hist, hist, 255, NORM_L1);
This should mean that the sum of every values inside the mat should equal to = 255
But later if i sum all values i get another value
sum(hist) != 255
To fix this error I need to call the normalize function like this:
normalize(hist, hist, 255, 0, NORM_L1);
Now I get:
sum(hist) == 255
Is this an intended behavior ?
