Detecting similar and identical images using perseptual hashes - Hacker Labs. Couple of my hobbies are travelling and photography.
I love to take pictures and experiment with photography. Usually after my trips, I just copy the photos to either my iPad or couple of my external hard disks. After 10 years, I have over 200K photos distributed across several disks and machines. pHash.org: Home of pHash, the open source perceptual hash library. Mperham/phashion. Theory.
