Measuring correlation between original image and binary image

[wajih7]

Hello everybody,
i want to evaluate the performance of every type of thresholding ( background correction , niblack, metric , entropy etc...) by measuring the correlation between the original image and the thresholded image.

i thought i did something illegal , sorry 

[wajih7]

i need suggestion , guidance 🙂

ok now could tell what you want to do indeed
