Vision IMAQ correlate for correlation between two images

[ravirocks43]

I am working on Imaq correlate vi for seeing the difference between two images. I have attached  the VI here. I would like to know how to interpret the output of vision imaq correlate in the form of values in pixel arrays or to know what is the difference between two images in pixel ( shift in pixels from these two images) as I only see the output picture but I want to know the difference in numeric value between two images.
