A Dynamic Frequency Selection Module for Geometry-Aware Building Extraction in VHR Remote Sensing Image (opens in new tab)

Reliable measurement of building footprints, encompassing precise boundary localization and planar area estimation, is fundamental to urban applications using very high-resolution (VHR) remote sensing imagery. Conventional semantic segmentation pipelines optimize pixel-wise accuracy but often suffer from blurred edges and shape distortions, leading to biased geometric measurements. Although recent frequency-domain methods attempt to recover structural details, they typically rely on static fi...
