WebJan 5, 2024 · For instance, Density Sensitive Hashing (DSH) [13] explored the geometric structure of the data to avoid a purely random projections selection. Spherical Hashing (SpH) [14] presented a hypersphere to construct a hash function and defined a new Hamming distance to improve the retrieval precision. The closest to our FCH method are … WebSpherical hashing is a way to compute a binary encoding of a feature vector while still maintaining spatial coherence. This binary encoding can then be used for an approximate …
WebSep 28, 2024 · For shorter codes (128-bits and below) only three hashing methods: Isotropic Hashing [ 6 ], Spherical Hashing [ 4] and Spectral Hashing [ 19] yield better accuracy. For 128-bit codes, the advantage of best methods over a naive bit truncation is minimal (1–2%). For the shorter codes best hashing methods perform noticeably better.
