Hashing images
WebAug 26, 2024 · The main challenge in image hashing techniques is robust feature extraction, which generates the same or similar hashes in images that are visually identical. In this article, we present a short review of the state-of-the-art traditional perceptual hashing and deep learning -based perceptual hashing methods, identifying the best approaches. WebMay 11, 2024 · However, for the use case of finding duplicate images we need to use a perceptual hash function (in contrast to a cryptographic hash function). A function that is commonly used in this context is the difference hash (dHash). Given an image and the desired size of the hash, the dHash can easily be calculated in a few lines of Python:
