View Blockhash on Github: JavaScript | Python | C | Experimental video code Welcome to Blockhash. Blockhash is a set of libraries (Python and JavaScript, currently) implementing a variation of the perceptual image hashing algorithm described by Bian Yang, Fan Gu and Xiamu Niu in their paper Block Mean Value Based Image Perceptual Hashing The 256 bit hashes that Blockhash generate are designed to be near unique for images, even after an image has been rescaled. The Hamming distance between two hashes (the number of bits that differ) indicate how far apart two images are, with single-digit values generally giving a good indication that the images are identical, even if they are of different size. Experimental video support Through 2016, we experimented with using the Blockhash algorithm to fingerprint videos. You can read more about the Videorooter project, and view our experimental video support.
