latest research papers on road extraction

The applications of the high resolution rs image processing mainly include the following aspects city remote sensing, basic geographic mapping, environmental monitoring and assessment, precision agriculture, and public information service, etc ( ). In this paper, after analyzing different road features and road models, the road extraction methods were classified into the classification-based methods, knowledge-based methods, mathematical morphology, active contour model, and dynamic programming. The road width is designed at different levels to meet different requirements.

Then, the comparisons of the different road extraction algorithms were performed, including road features, test samples and shortcomings. All of those high resolution rs images such as ikonos, quickbird, worldview and geoeye create a quick and economical way to access the newly acquired geographic information, and lay a very important basis for the further applications of rs technology. The conclusions are presented in section the difficulties of road extraction from rs images lie in that the image characteristics of road features can be affected by the sensor type, spectral and spatial resolution, weather, light variation, and ground characteristic, etc.

Rs image, which is shown in in practice, the rs image quality can be affected by different factors such as the sensor type, spectral and spatial resolution, weather, light variation, and ground characteristic, etc. In general, we have to make an image enhancement so as to extract useful information from a rs image.

Textures in an image have the regional characteristics, which are a kind of visual features to reflect the homogeneity phenomenon in the image.

    Automated road extraction from high-resolution satellite imagery ...
    The research in this thesis focuses on the development of effective methods to extract roads ... The first one is a semi-automated road extraction method based on. ... in the latest high-resolution satellite images, such as IKONOS and QuickBird, ...

    Geometric features have the direct relationships with the road shapes. Roads are the backbone and essential modes of transportation, providing many different supports for human civilization. .

    In this paper, after analyzing different road features and road models, the road extraction methods were classified into the classification-based methods, knowledge-based methods, mathematical morphology, active contour model, and dynamic programming. In the bad weather, the vague gray value difference between road and background makes the road edge fuzzy, which leads to a bad segmentation result. All of those high resolution rs images such as ikonos, quickbird, worldview and geoeye create a quick and economical way to access the newly acquired geographic information, and lay a very important basis for the further applications of rs technology.

    The road junctions usually can be presented as the signs of t, y, or. Article suggestions will be shown in a dialog on return to sciencedirect. The essence of texture features is to find the spatial distribution of pixel gray levels in the neighborhood ( different road features in an image have different properties for road extraction. It has nothing to do with the color and intensity information.
