Deep Unsupervised Contrastive Hashing for Large-Scale Cross-Modal Text-Image Retrieval in Remote Sensing. (arXiv:2201.08125v1 [cs.CV])

Due to the availability of large-scale multi-modal data (e.g., satellite
images acquired by different sensors, text sentences, etc) archives, the
development of cross-modal retrieval systems that can search and retrieve
semantically relevant data across different modalities based on a query in any
modality has attracted great attention in RS. In this paper, we focus our
attention on cross-modal text-image retrieval, where queries from one modality
(e.g., text) can be matched to archive entries from another (e.g., image). Most
of the …
