Distributed video coding (DVC) is considered to be a potential solution for various applications, e.g. wireless multimedia sensor networks, mobile devices, owing to the feature of easy encoding/complex decoding. However, practical DVC systems still have a rate distortion (RD) performance gap with respect to the traditional video coding standards with complex encoding/easy decoding. Side information, created at the DVC d Read More

To improve the transfer efficiency of urban passenger hub, the platforms, stations and transfer routes were expressed as variables based on Graph theory. The calculation methods for passenger transfer time of the routes were developed based on regression model. Conflict level of traffic flow was measured by a weighting model. A bi-level programming model was brought forward, where the upper level was transfer time mini Read More

The path following control strategies for a six-wheel lunar rover under loose soil terrains were proposed after building the rover sideslip model, as well as the sideslip and slippage model of each wheel. The design of controller was done using the prior layered hierarchical architecture. The path following control level only considered the sideslip of rover. The inner control level took the sideslip and slip of each wheel as corrections Read More

Water hazard is one of the most dangerous obstacles for unmanned vehicle to travel in off-road environment. The vision information for water hazard body includes relatively high brightness, low saturation and smooth texture. In this paper, static image and sequence image are captured by CCD. Color and texture information extracted from image pixels would be utilized to form a feature matrix to train the SVM classifier. W Read More

Today more and more people have concerned about how to reduce the energy consumption of vehicles on road in urban city. This paper uses the petrol car as research object, researching the energy saving of vehicles in conditions of real urban transportation. The best travel route of the energy saving is found by comparing different travel routes, and it is finally proved that there exists a travel route that may not be the s Read More
