Multi-source heterogeneous feature fusion and multi-scale edge enhancement method for open-pit mining land cover segmentation

Accurate land cover classification in mining areas is essential for environmental monitoring and resource management. However, this task is hindered by complex spectral-spatial characteristics and highly fragmented landscapes, where traditional single-source spectral analysis often fails to resolve “spectral ambiguity” among disparate land covers. To address this, we propose a Dual-Branch UNet (DB…
