Supervised Hashing with End-to-End Binary Deep Neural Network
Dang-Khoa Le Tan, Thanh-Toan Do, Ngai‐Man Cheung · 2018
Image hashing is a popular technique applied to large scale content-based visual retrieval due to its compact and efficient binary codes. Our work proposes a new end-to-end deep network architecture for supervised hashing which directly learns binary codes from input images and maintains hashing properties, namely similarity preservation, independence, and balancing. Furthermore, we also propose a new learning scheme that copes with the binary constrained loss function. The proposed algorithm not only is scalable for learning over large-scale datasets but also outperforms state-of-the-art supervised hashing methods, which are illustrated throughout extensive experiments from various image retrieval benchmarks.
