In another study [ 3 ], an image hashing algorithm based on the color vector angle (CVA) and discrete wavelet transform (DWT) was proposed. This algorithm has good robustness for JPEG compression and small-angle rotation.
WebAs satellite observation technology rapidly develops, the number of remote sensing (RS) images dramatically increases, and this leads RS image retrieval tasks to be more challenging in terms of speed and accuracy. Recently, an increasing number of researchers have turned their attention to this issue, as well as hashing algorithms, which map real … WebThe elliptic curve only hash (ECOH) algorithm was submitted as a candidate for SHA-3 in the NIST hash function competition.However, it was rejected in the beginning of the competition since a second pre-image attack was found.. The ECOH is based on the MuHASH hash algorithm, that has not yet been successfully attacked.However, …
Web30 apr. 2024 · Image Hashing Another way to compute the similarity between two images is Image hashing (also known as digital fingerprinting). It is the process of assigning unique hash values to every image. However, the method results in the same value for identicals. Average hashing is one of the many types of hashing. It works in the following way [ 6 ].
