Learning hash codes
Nettetchine learning techniques to produce more effective hash codes [16]. The goal of learning to hash is to learn data-dependent and task-specific hash functions that yield com-pact binary codes to achieve good search accuracy [17]. In order to achieve this goal, sophisticated machine learn-ing tools and algorithms have been adapted to the proce- Nettetcess into a stage of learning approximate hash codes, fol-lowed by a deep-networks-based stage of simultaneously learning image features and hash functions, with the raw image pixels as input. However, a limitation in CNNH is that the learned image representation (in Stage 2) cannot be used to improve the learning of approximate …

Nettet1. aug. 2024 · Download PDF Abstract: Existing data-dependent hashing methods usually learn hash functions from pairwise or triplet data relationships, which only capture the data similarity locally, and often suffer from low learning efficiency and low collision rate. In this work, we propose a new \emph{global} similarity metric, termed as \emph{central … Nettet1. jan. 2024 · Finally, a binary hash code (BHC) learning model is generated to embed high-dimensional dense finger vein features into Hamming space. In testing stage, for a given finger vein image in probe set, NSC feature are first extracted from the preprocessed ROI image. After that, NSC feature is fed into the binary hash code learning model to …
