MCANet: A joint semantic segmentation framework of optical and SAR images for land use classification
Open accessAbstract
Deep convolution neural network (DCNN) is among the most effective ways of performing land use classification of high-resolution remote sensing images. Land use classification by fusing optical and synthetic aperture radar (SAR) images has broad application prospects, but related research studies are few. In this study, we developed the first and largest joint optical and SAR land use classification dataset, WHU-OPT-SAR, covering an area of approximately 50,000 km2, and designed a multimodal-cross attention network (MCANet). MCANet comprises three core modules: the pseudo-siamese feature extraction module, multimodal-cross attention module, and low-high level feature fusion module, which are used for independent feature extraction of optical and SAR images, second-order hidden feature mining, and multi-scale feature fusion. The land use classification accuracy of our approach on the WHU-OPT-SAR dataset was approximately 5% higher than that of optic-image-based approaches. Moreover, the accuracy of city,village,road,water,forest, and farmland classification was improved by 7%, 2%, 5%, 6%, 1%, and 0.6%, respectively, reflecting the superior performance of fusing optical and SAR images. Furthermore, the classification accuracy in Hubei Province of China, which covers an area of 190,000 km2, has also increased by approximately 5%, which verifies the effectiveness of our approach.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
