PolyBuilding: Polygon Transformer for End-to-End Building Extraction. (arXiv:2211.01589v1 [cs.CV])

We present PolyBuilding, a fully end-to-end polygon Transformer for building
extraction. PolyBuilding direct predicts vector representation of buildings
from remote sensing images. It builds upon an encoder-decoder transformer
architecture and simultaneously outputs building bounding boxes and polygons.
Given a set of polygon queries, the model learns the relations among them and
encodes context information from the image to predict the final set of building
polygons with fixed vertex numbers. Corner classification is performed to
distinguish the building corners from the …
