WebApr 2, 2024 · The proposed method can obtain high matching accuracy through hash index in a very short amount of time. The core of hash matching includes two parts: creating the hash table and hash index. The former is used to encode local feature descriptors into hash codes, and the latter is used to search candidates for query feature points. WebFeb 13, 2024 · Hashing is a technique to retrieve information in a secure and quick way. In hashing, we define a method to store and retrieve the information in the system. Suppose we have an array of elements with a limited range, we store these elements in the array in such a way that we can search/find the element in O (1) time when it is required.
