In order to classify the eaglewood, the work proposed a method of wood fiber segmentation and characteristic extraction based on the eaglewood micrographs. The active contour model was used to extract the contours of the eaglewood micrographs. After screening of wood fiber, the geometric features and shape factors were extracted to form characteristic vectors. After that, SVM was used to achieve the...
Stereo-footprint is a vital trace evidence of criminal detection. Thus, it is important to make a high accuracy feature extraction of the stereo-footprint. In this paper, a system of stereo-footprint data acquisition-recognition is designed. In the system, feature extraction is completed through CP35MHT80 which offered by Wenglor, image extraction is gotten through C920 which is offered by Logitech...
This paper illustrates a novel formal method of component integrating for component-based development in safety critical area. Formal definitions of COTS component and safety verification method are presented, as well as a development framework is shown. Furthermore, we demonstrate a case study of zone controller (ZC) from railway communications-based train control system, with the help of tool set...
In multi-hop relay network, there may be several Relay Nodes(RNs) subordinated to the base station(BS) in a cell. When an user equipment (UE) moves from one cell to another, or an UE moves between two different RNs, a handover will happen. Since the coverage of a relay is small, the handover between two RNs or RN and base station (BS) maybe happen frequently. In terms of whether the UE is located...
