Researchers have developed ShadowCast, a novel method for improving semantic segmentation in remote sensing images by synthesizing and injecting shadows during the training phase. This approach leverages existing segmentation labels to extract masks of elevated objects and estimates a shadow direction cue to project synthetic shadows. Unlike previous methods that treat shadows as degradations, ShadowCast uses them as a complementary augmentation strategy. Experiments on the Vaihingen, Potsdam, and LoveDA datasets demonstrate that ShadowCast consistently enhances the performance of various segmentation architectures. AI
