Automatic Road Network Extraction by Hierarchical Grouping
نویسندگان
چکیده
This paper presents an automatic method for road network extraction from low-resolution images using hierarchical grouping. The method consists of three major steps: firstly it extracts lines from original images and generates smooth lines in a split-and-merge operation; a hierarchy of line images is generated using different thresholds for line length, based on the extracted line images; the linear features in the line images are then grouped hierarchically. Finally, knowledge of road networks is applied to remove non-road segments to form a complete road network. The paper includes results of tests on the implementation of these procedures.

متن کاملAutomatic Road Detection and Extraction From MultiSpectral Images Using a New Hierarchical Object-based Method
Road detection and Extraction is one of the most important issues in photogrammetry, remote sensing and machine vision. A great deal of research has been done in this area based on multispectral images, which are mostly relatively good results. In this paper, a novel automated and hierarchical object-based method for detecting and extracting of roads is proposed. This research is based on the M...
متن کاملAutomatic Extraction of Main Road Centerlines from High Resolution Satellite Imagery Using Hierarchical Grouping
Automatic road centerline extraction from high-resolution satellite imagery has gained considerable interest recently due to the increasing availability of commercial high-resolution satellite images. In this paper, a hierarchical grouping strategy is proposed to automatically extract main road centerlines from high-resolution satellite imagery. Here hierarchical grouping means that, instead of...
متن کاملExtraction of Roads from Aerial Imagery Based on Grouping and Local Context
This paper addresses the automatic extraction of roads from aerial imagery. As only the automatic extraction of parts of the road network is possible in a single step, grouping is an inherent problem. For this a road extraction scheme based on iterative local grouping of “road objects” is proposed. Apart from geometric grouping cues and radiometric attributes also information about local contex...
متن کاملObject-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
