WebFeb 19, 2015 · Cloudinary uses perceptual hash (pHash), which acts as an image fingerprint. This mathematical algorithm analyzes an image’s content and represents it using a 64-bit number fingerprint. Two images’ pHash values are “close” to one another if the images’ content features are similar. By comparing two image fingerprints, you can tell if ... WebMar 5, 2024 · 16. By using the image hashing approach we can store a unique fingerprint for each of our images in our database to help us identify identical or visually similar images by comparing the hash of a new image with one of the hashes we’ve calculated before. The hashes are small, quick to search, and the technique is really effective.
