I was trying to install using

pip install fingerprint

but it gives an error

But older version

pip install fingerprint==0.1.1

works fine though.

Hi,

I was using your algorithm to classify different documents and while it was working well, for some reason when I apply OCR to handwritten forms (text is valid I have checked) somehow none of the hashed fingerprints match another similar form. I have attached the two forms I am comparing along with this issue. Any help on this is appreciated!

These are IRS forms (1099) and I have filled one with random data on a page and the other one is just a template. I want to see if there is a similarity in their fingerprints (which there should be), but it shows no common fingerprints.

f1099msc.txt
1099_2.txt

fpg = FingerprintGenerator(input_string='asdfsdfasfadafafadsadfa')
fpg.generate_fingerprints()

Hi, I ran into a problem when importing a module. I use python 3. Please tell me how to solve my problem. Thanks!

Hi,

I was looking at your implementation of winnowing and decided to try it out on a project I am working on. I have .txt files that I am using this on to create digital fingerprints for these files. With the kgram length as 5 and a window length of 19 (therefore expected keys selected should be close to 2/(1+window length) = 10%), I am getting around 50% of my hashes as fingerprints. Out of this 50%, around 85% have a value of 0 in different positions. Do you have any idea why this could be the case?
