This paper presents a novel framework, namely Deep Cross-modality Spectral Hashing
(DCSH), to tackle the unsupervised learning problem of binary hash codes for efficient cross …

Hashing based approximate nearest neighbor search embeds high dimensional data to
compact binary codes, which enables efficient similarity search and storage. However, the …

Face video retrieval has drawn considerable research attention recently. Most prior research
mainly focused on either appearance features or correlation features, which could degrade …
