Road extraction plays an important role in urban planning and city extension issues, as well road monitoring, traffic management map updating. Technological advances may offer a wealth of data techniques that could be implemented delineation extraction, change detection projects. Among the various methods have been developed for this purpose, remote sensing especially digital processing satelli...

Internal self-diagnosis and external evaluation of the obtained results are of major importance for the relevance of any automatic system for practical applications. Obviously, this statement is also true for automatic image analysis in photogrammetry and remote sensing. Recently, automatic systems for the extraction of road networks reached a state in which a systematic evaluation of the resul...

Automatic linear feature extraction has a long history but still it is one of the challenging topics in photogrammetry and computer vision. In this paper, we describe an automatic road extraction process suitable for urban areas with high buildings. The proposed road extraction process has roughly three steps. The first step is generating an obstacle map to get road primitives from the digital ...

A robust skin detector is the primary need of many fields of computer vision, including face detection, gesture recognition, and pornography filtering. Less than 10 years ago, the first paper on automatic pornography filtering was published. Since then, different researchers claim different color spaces to be the best choice for skin detection in pornography filtering. Unfortunately, no com...

Computer Vision based autonomous robot navigation has caught the attention of many researchers because of its huge potential in various industrial and social applications. This paper focuses on various approaches used to detect road region which is fundamental requirement in applications like intelligent vehicles, lane detection and tracking and driver assistance systems. Broadly speaking techn...

Automatic extraction of linear topographic objects, such as, roads, rivers, or power lines, is an important topic for topographic mapping. In case of roads, an automatic extraction from Synthetic Aperture Radar (SAR) imagery is rather difficult, due to the speckle effect and the limited spatial resolution in relation to the road width. In this paper we investigate the additional use of multifre...

Road detection is the major task of autonomous vehicle guidance. We notice that feature lines, which are parallel to the road boundaries, are reliable cues for road detection in urban traffic. Therefore we present a real-time method that extracts the most likely road model using a set of feature-line-pairs (FLPs). Unlike the traditional methods that extract a single line, we extract the feature...
