| Summary: | Accurate coastal zone change detection is crucial for coastal urban planning and marine resource development. To address the specificity of coastal zone change detection and the category imbalance issue in the model, we propose a multi-scale coastal zone change detection method (AMMNet) based on the attention mechanism. The method leverages multi-scale features extracted by the ResNet backbone, which are then optimized and integrated through high-frequency attention and spatio-temporal difference modules. These modules allow the model to focus on both global and local changes, enhancing its ability to detect variations in coastal zones. Additionally, the foreground attention module refines the model’s attention on relevant regions, ensuring improved performance. The experimental results show that our method achieves the highest scores in several evaluation metrics, demonstrating significant advantages in accuracy and generalization and effectively addressing the category imbalance problem. It provides a robust solution for coastal zone change detection. |
