چکیده

Update of geographic information systems (GIS) is very important. So far it is done mainly manually. In this paper we propose an approach for the automatic veriication of roads. It is a rst step towards a more automatic update procedure. The approach is based on up-to-date aerial images as well as GIS data. In the surroundings of GIS road-axes candidates for roadsides are searched for in the image based on prooles. The candidates for roadsides are tested and a measure of conn-dence is calculated for the corresponding GIS road-axes. This leads to a classiication of the GIS road-axes into veriied, asymmetric and rejected. Practical examples for aerial images of diierent complexity are given.

Automatic 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...

Automatic Proole Identiication

This paper presents a practical implementation of a person veriication system based on face prooles in a cooperative environment. The image acquisition constraints are given and motivated. A set of global and local features are automatically extracted from the proole outline of the head. The candidate proole is then compared with prooles of the database to issue a distance from which to accept ...

Reducing Light Change Effects in Automatic Road Detection

Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...

Fuzzy Neighbor Voting for Automatic Image Annotation

With quick development of digital images and the availability of imaging tools, massive amounts of images are created. Therefore, efficient management and suitable retrieval, especially by computers, is one of themost challenging fields in image processing. Automatic image annotation (AIA) or refers to attaching words, keywords or comments to an image or to a selected part of it. In this paper,...
