Preprocess images in the library to define the important features which 
distinguish every image from all others. When comparing an image to the 
library set, compare the features only.

Hash can only tell the exact match.

I can.

Oh, dear Sir. Your "thank you" means a lot to me. Just $100 would be enough.

Hello!
I prepared a library of 40 images. I want to create a search to find the
best fitting image out of the 40 in the library to a new unknown image. For
now, I'm assuming all images are the same size and are binary. The search
can, for instance, be between 40 binary matrixes to a new binary matrix or
between 40 binary vectors to a new unknown binary vector. It's important
for me to find an efficient search in terms of calculation time. I thought
about using hashes.
Can anyone help me? Thank you very much
