Mapping the extent of giant Antarctic icebergs with deep learning
13 November 2023
In this study, the authors propose a deep neural network to map the extent of giant Antarctic icebergs in Sentinel-1 images automatically. While each manual delineation requires several minutes, their U-net takes less than 0.01 s. In terms of accuracy, they find that U-net outperforms two standard segmentation techniques (Otsu, k-means) in most metrics and is more robust to challenging scenes with sea ice, coast and other icebergs. The absolute median deviation in iceberg area across 191 images is 4.1 %.
