Road extraction from digital images: methodologies developed by the GP-F&VC
Abstract
Several kinds of research in road extraction have been carried out in the last 6
years by the Photogrammetry and Computer Vision Research Group (GPF&
VC - Grupo de Pesquisa em Fotogrametria e Visão Computacional).
Several semi-automatic road extraction methodologies have been developed,
including sequential and optimization techniques. The GP-F&VC has also been
developing fully automatic methodologies for road extraction. This paper
presents an overview of the GP-F&VC research in road extraction from digital images, along with examples of results obtained by the developed
methodologies.
