Hello pHash team,
I am wondering how does one read the return value of the hamming distance function. While I understand that the smaller the value, the more similar the two hashes (consequently, the images), is there a rule of thumb on the interpretation of the actual value. E.g., "if hamming distance > 0.50, do not bother with the image".
Also on the same topic, what does the ph_hammingdistance2() value actually mean? E.g., "hamming distance of 0.4 means the hashes are 40% dissimilar", etc.
Thanks!
