Discrete hashing
WebMar 24, 2024 · Hashing can facilitate efficient retrieval and storage for large-scale images due to the binary representation. In the real applications, the trade-off between retrieval accuracy and speed is essential for designing a hashing framework, which is reflected by variable hash code lengths. In light of this, the existing hashing methods need to train … WebJul 8, 2024 · The domain adaptive hashing is defined as to learn a binary code matrix B ∈ {− 1,1} r×N and hash function f ( X ), where r is the length of hash codes. For an out-of-sample instance query x_ {t_ {i}}, it can generate hash codes b_ …
