Cloud Detection Using a UNet3+ Model with a Hybrid Swin Transformer and EfficientNet (UNet3+STE) for Very-High-Resolution Satellite Imagery

Remote Sensing
It is necessary to extract and recognize the cloud regions presented in imagery to generate satellite imagery as analysis-ready data (ARD). In this manuscript, we proposed a new deep learning model to detect cloud areas in very-high-resolution (VHR ...

Satellite scene classification using CoAtNet to assess suitability of browser images for analysis-ready data generation

KSCE Journal of Civil Engineering
Analysis-ready data (ARD) has attracted growing interest because it enables immediate downstream use of satellite imagery. Despite advances in preprocessing, many acquired images remain unsuitable for ARD generation due to quality-degrading factors. This
