This paper uses the software package, Unity, to create a virtual reality system. After virtual structures of automobile bodies, streets, and background were created, various weather conditions such as sunny, rainy, and snowy along with artificial variables such as sudden crossings by pedestrians, roadblocks, vehicle and scooter blind spots, and other emergency events that can easily occur while driving...
The development of information technology provide foundation to collect a large number of data for urban traffic management. These traffic data can be used to monitor traffic state surrounding the bottleneck and to analysis the evolution of the temporal and spatial rules of congestion. Based on the historical detector data, the new indexes have been proposed in this paper to evaluate the severity...
A wearable monitoring system for biker is presented, with textile-based clip type tension sensors on belt and pants to detect biker's breath and steps, respectively, and an accelerometer, together with clip type sensors to detect falling down and other biking conditions. The clip type sensors are fully made of textile, so they are washable, durable, low cost, easily installed on ordinary clothing,...
In this paper, we present a two-stage scheme for supervised classification of polarimetric interferometric synthetic aperture radar (PolInSAR) imagery. In the first stage, a regularized logistic regression classifier is employed to generate probability vectors of object labels with polarimetric and interferometric features, respectively. The soft outputs (probability map) of previous logistic classifier...
