EXTRACTION OF ROAD FROM SATELLITE RESOLUTION IMAGES USING MATLAB

Abstract

The importance of road extraction from satellite images arises from the fact that it greatly enhances the efficiency of map generation and it provide huge volume of data and monitor events and areas without any interference.This has motivated, dedicated and focused on the development of efficient and advanced methods for object detection and extraction from satellite images.Roads are important bowed object as they are used in urban planning, emergency response, route planning etc. Automatic road detection from satellite images has now become an important topic and roads play a vital role in urban planning and thus its extraction can be great helpful for human expertise.In this paper, to enhance the image and to strengthen the road feature with the surrounding environment color gradient we use some methods for road extraction from satellite images based on the concept histogram equalization, Otsu's method of image segmentation, median filter and edge detection operations of image processing.The experiment result of this paper is to discover the potential of high resolution satellite images for detecting and extracting the road network in a robust manner.
