Locality-sensitive hashing lsh technique
Witryna25 maj 2024 · Locality Sensitive Hashing (LSH) is a computationally efficient approach for finding nearest neighbors in large datasets. The main idea in LSH is to avoid having to compare every pair of data samples in a large dataset in order to find the nearest similar neighbors for the different data samples. With LSH, one can expect a data … WitrynaWe introduce a locality sensitive hashing (LSH) technique based on Odlyzko’s work that avoids any guessing of e’s coordinates. This LSH technique involves a …

The two best indexing techniques used for SIFT are kd-tree and k-means, try them. Both of them are implemented in FLANN matcher which is part of OpenCV. This two papers compares FLANN and LSH for SIFTs: "Locality sensitive hashing: a comparison of hash function types and querying mechanisms".
Witrynalied on a new method called locality-sensitive hashing (LSH). The key idea is to hash the points using several hash functions so as to ensure that, for each function, the probability of collision is much higher for objectswhich are close toeach other than forthose which are far apart. Then, one can determine near neighbors by hashing
