Max Score is infinity when using Mask for Template Matching

[ShiddhamSharma]

I used Mode as CCorr and it worked fine by finding the correct location.
Why is the denominator zero then when I am trying to do normalization?

I checked the formula for CCORR and understood why this problem might be there.
My image is also thresholded and has much larger areas with black values.
Because of this, the denominator for the summation of intensity at given locations in the image with the mask might come out as zero. Though the numerator must also be zero, it somehow gives such cases as infinity.
For this, I went element by element and converted the cases where score is greater than 1 to -1.
After this it is working fine.
Let me know if there is any other short way?
