Aging roads and poor road-maintenance systems result a large number of potholes, whose numbers increase over time. Potholes jeopardize road safety and transportation efficiency. Moreover, they are often a contributing factor to car accidents. To address the problems associated with potholes, the locations and size of potholes must be determined quickly. Sophisticated road-maintenance strategies...

The main factor affecting road performance is pavement damage. One of the difficulties in maintaining roads cracking. Credible and reliable inspection heritage structural health relies heavily on crack detection surfaces. To achieve intelligent operation maintenance, essential to traffic safety. cracks using computer vision has gained popularity recent years. Recent technological breakthroughs ...

In this paper, we propose an approach for automatic generation of novel intrusion signatures. This approach can be used in the signature-based Network Intrusion Detection Systems (NIDSs) and for the automation of the process of intrusion detection in these systems. In the proposed approach, first, by using several one-class classifiers, the profile of the normal network traffic is established. ...

Road extraction plays an important role in many applications such as car navigation. However, the manual extraction of roads is a laborious and tedious task. Road extraction from satellite images has drawn considerable attention in last years due to the recent availability of commercial high-resolution optical satellite imagery. Road extraction strategies are usually classified into two categor...

A method for the automatic detection and recognition of text and symbols painted on the road surface is presented. Candidate regions are detected as maximally stable extremal regions (MSER) in a frame which has been transformed into an inverse perspective mapping (IPM) image, showing the road surface with the effects of perspective distortion removed. Detected candidates are then sorted into wo...

In this paper, we present a semi-automatic road extraction method based on a piecewise parabola model with 0-order continuity. The piecewise parabola model is constructed by seed points coarsely placed by a human operator. In this case, road extraction actually becomes a physical problem of solving of each piece of parabola with only two or three unknown parameters by using image constraints. W...

An approach for the automatic extraction of roads ftom digital aeria)-imagery is proposed. It makes use of several versions of the saie aeriaT image with differcnt reso-lutions' Roads ate modeled as a network of intersections and links between these intersections, and are found by a grouping prccess. The context of roads is hierarchically structured into a globd and a Local level. The automatic...

Last years witnessed the growth of demand for road monitoring systems based on image or video analysis. These systems usually consist of a survey vehicle equipped with photo and video cameras, laser scanners and other instruments. Sensors mounted on the van collect different types of data while the vehicle goes along the road. Recorded video can be geographically referenced with the help of glo...

Autonomous road following is a domain which spans a range of complexity from p r l y defmed, unmarked dirt roads to well defined, well marked, highly structured highways. The YARF system (for Yet Another Road Follower) is designed to operate in the middle of this range of complexity, driving on laban streets. Our research program has focused on the use of featureand situation-specific segmentat...
