HFER-SAM: Boundary-Aware Segment Anything Model via High-Frequency Enhanced and Residual Injection for Building Extraction

Automatic building extraction from high-resolution remote sensing imagery is vital for urban applications. Although the Segment Anything Model (SAM) offers powerful semantic capabilities, its direct application faces severe challenges. The inherent low-pass filtering of Vision Transformers typically causes blurred buil...
