INTRODUCTION
This is AMFMN, a cross-modal retrieval method for remote sensing images. Here, you can get the benchmark of the image-text cross-modal retrieval method, which can be further modified to obtain higher retrieval accuracy. Next, we will publish the more fine-grained image-text RSITMD dataset, and welcome you to use the proposed dataset.
AMFMN
Network Architecture
Asymmetric multimodal feature matching network for RS image-text retrieval. AMFMN uses the MVSA module to obtain salient image features and uses salient features to guide the representation of text modalities. The network supports multiple retrieval methods and can adaptively fuse different modal text information.
RSITMD
Dataset Features
The similarity visualization results of six datasets, where the similarity score is weighted by the BLEU and METEOR indicators in the natural
language processing field. The ideal picture is a straight diagonal line from the upper left to the lower right, which means each sentence is only related to the
corresponding image.
Quantitative comparison of the four datasets. (a) Comparison of sample number. (b) Comparison of average sentence length. (c) Comparison of
diversity score. (d) Comparison of average similarity. (e) Comparison of the total number of words. (f) Comparison of the number of categories.
