Opencv img hash

Web20 de abr. de 2024 · That depends on the purpose of the hash. For testing if two images are identical by comparing the hashes, 64 bits is enough (probability of 1 in 2^64 to get wrong result). For cryptographic hash (preventing someone from forging an image with the same hash), use more then 64 bits. Web9 de mar. de 2024 · 1. The main thing is to register the logo and the template. As your images are quasi binary and contain only the logo, you can rely on the computation of moments. You will compute them for the binarized image and the binarized template. The zeroth order moment of the black pixels is the area.
