    We propose a vehicle tracking algorithm that takes a new occlusion reasoning approach. We consider two different types of occlusions: explicit occlusion and implicit occlusion. We also propose a traffic flow extraction method with the velocity and trajectory of the moving vehicles. The proposed vehicle tracking system is composed of three parts: vehicle segmentation, vehicle tracking, and traffic ... View full abstract»

    Travel time information is important for traffic control systems. If a toll collection system is adopted, we can calculate travel-time from toll collection system data. Little attention has been given to this because of the following problems. Unusual-data (data deviating from the main distribution of travel time data) removal is difficult. When there is only a small number of data, it is difficul... View full abstract»

    The paper describes a system for detecting vehicles in urban traffic scenes in daytime and at night by means of image analysis and rule-based reasoning. The strength of the proposed approach is its formal separation between the low-level image processing modules (detecting moving vehicles under day and night light) and the high-level module, which provides a single framework for tracking vehicles ...

    Since any-time behavior allows a tradeoff between solution quality and search time, any-time algorithms are very useful for automotive applications in which robustness and real-time processing plays a significant role. In general, any-time algorithms have the property that a solution is ready whenever the algorithm is stopped and the solution improves with additional computing time. We make use of...
