Exploring Self-Image and Cross-Image Consistency Learning for Remote Sensing Burned Area Segmentation

The increasing frequency of global wildfires has led to the destruction of vast forests and wetlands. Non-contact remote sensing technologies provide an effective means for accurate burned area segmentation (BAS). However, existing BAS methods often treat each image independently, focusing primarily on local pixel contexts while neglecting the broader semantic consistency of burned regions across different scenes. The lack of global context modeling limits their robustness, as burned areas typically exhibit distinctive and consistent visual characteristics such as color and texture across diverse environments. To address this limitation, we propose a Self-image and Cross-image Consistency Learning (SCCL) framework, which captures both local pixel-level relationships within a single image and global semantic dependencies across multiple images. By enforcing consistent and compact representations of burned regions within and across images, SCCL enhances segmentation robustness under varying weather and terrain conditions. Additionally, to refine boundary delineation between burned and unburned areas, we introduce a Burned Edge Injector (BEI) and an Edge-Injected Decoder (EID). We further construct two large-scale BAS benchmark datasets, BAS-AUS and BAS-EUR, for comprehensive evaluation. Experiments on these benchmarks demonstrate that our method achieves state-of-the-art performance, significantly outperforming previous approaches, with MAE reduced to 0.017 and 0.016, respectively.
