Year by year, traffic congestion is severe on street in big cities such as Tokyo because vehicles increase rapidly compared to constant street surface. Furthermore, this problem causes economic and environmental waste. Therefore the attempt to monitor vehicles and their behaviors becomes challenging demanding unavoidably on vehicle statistical analysis for efficient and effective traffic planni...

The aim of this study is to develop automatic road extraction algorithm in satellite images. As roads have different width and surface material characteristics in urban and rural areas, a modular approach for road extraction algorithm is desired. In this study, edge detection, segmentation, clustering and vegetation and land cover analyses are used. In order to combine the results of different ...

A new algorithm of automatic extraction of thin structures in textured images is introduced, and, more specifically, is applied to detection of road cracks. The method is based on two steps: the first one consists in detecting points of interest inside the thin structure whereas the second step connects the points with a geodesic contour process. The main contribution of this work is the study ...

Road signs are very important features for providing rules of navigation. Indeed, they are key landmarks when navigating on the roads. Their visual properties are very strong because they have been designed to be remarkable and unmissible objects. Road signs are thus key objects to enrich road model databases to generate roadbooks, shortest paths, etc. The automatic detection and recognition of...

After extensive research work of several decades, automotive radars are finally pushing into consumer market. Commercially available radars are either for automatic cruise control or blind spot detection. Automatic cruise control systems adjust the vehicle speed according to the preceding vehicle whereas blind spot detection systems ease certain maneuvering, such as lane changing. Automotive ra...

The Three Line Scanner or TLS Technology has emerged for the few years. The merit characteristic of Three Line Scanner distributes the digital image with very high spatial resolution, few centimeters. By meanwhile, the traffic problem in mega city remains more and more severe such as Traffic congestion, Accident etc. Moreover, due to human and time-consuming process by manual vehicle counting, ...
