Research on Automatic Road Extraction Based on Perceptual Organization
Yan Li · Remote Sensing Information · 2005
Firstly this paper introduces the cognitive psychology and perceptual theory briefly. Then an automatic approach of extracting road based on road model and perceptual organization is presented. This method utilizes the global information to lead the road segments regrouping and uses the Heuristic Graph Search Algorithm-A* algorithm to link the curve parts of road, which improves the result of local grouping and enhances the reliability of road extraction greatly.
