Mapping mountain glaciers using an improved U-Net model with cSE

Global warming is melting glaciers. Changes in mountain glaciers have a tremendous impact on human life. Regular identification and extraction of from satellite images are necessary. However, when studying glaciers, materials surrounding the glacier high spectral similarity to easily misclassified process. Therefore, this study extraction, we used an improved U-Net model (a channel-attention U-Net) map The was trained Landsat 8 Operational Land Imager (OLI) data Shuttle Radar Topography Mission (SRTM) digital elevation (DEM), tested Pamir Plateau. results show that identifies with relatively accuracy compared GlacierNet. obtained were fine-tuned by conditional random field model, effectively reducing background misidentification.
