i have tried several times to find position of sub-image inside the bigger image, and i found out that i must substract the mean of the images for it.
i still couldn't understand why.
can someone help please?

I am not sure the complete process that you are following, but subtraction with mean Image is generally done to center the image. It is a common preprocessing step for most Image Processing algorithms.
Hope this helps!
