Unsupervised Contrastive Hashing for Cross-Modal Retrieval in Remote Sensing. (arXiv:2204.08707v1 [cs.CV])

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 remote sensing (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 existing cross-modal text-image retrieval systems in RS
require a high number of labeled training samples and also …
