PolyBuild: An End-to-End Method for Polygonal Building Contour Extraction from High-Resolution Remote Sensing Images
Researchers have developed PolyBuild, a novel end-to-end method for extracting building polygon contours directly from high-resolution remote sensing images. This approach bypasses the need for computationally intensive post-processing steps common in existing methods. PolyBuild utilizes an Initial Contour Generation Module for initial extraction and a Contour Optimization Module, incorporating CNN and Transformer features, to refine the contours, achieving superior performance on multiple datasets.
