基于USB的WSN测试与分析系统

实时监控无线传感器网络（WSN）从单个节点到整个网络的运行状态,是进行无线传感器各类研究及应用开发的关键技术之一,为了克服基于UART的数据传输所存在的速率瓶颈问题,设计了一种基于USB的WSN监测系统,主要包括侦听节点和监测分析系统两部分。侦听节点采用CC2531 USB Dongle,以被动侦听的方式获取无线传感器网络的数据包（符合IEEE802.15.4标准）,封装后通过USB接口上传至上位机监测分析系统。上位机监测系统,通过USB接口读取数据帧、完成帧信息存储、解析。实验结果表明该设计能够实现数据传输并以图形方式动态显示网络运行状态。本监测系统的设计为开展WSN的各类理论及实验研究提供了有力的分析工具。

Subspace morphing theory for appearance based object identification

Object identification techniques have wide applications ranging from industry, business, military, law enforcement, to people's daily life. This research is motivated to develop a new theory for appearance based object identification with its applications in different areas. Although many successful techniques have been proposed in certain specific applications, object identification, in general, still remains as a difficult and challenging problem. In appearance based approaches, almost all the proposed methods are based on a fundamental assumption, i.e., all the images (both in the model base and to be queried) are in the same dimensions, so that the feature vectors are all in the same feature space; if images are provided with different dimensions, a normalization in scale to a pre-determined image space must be conducted. In this research, a theory for appearance based object identification called subspace morphing is developed, which allows scale-invariant identification of images of objects, and therefore, does not require normalization. Theoretical analysis and experimental evaluation show that in the situation where images are provided in different dimensions, which is common in many applications, subspace morphing theory is superior to the existing, normalization-based techniques in performance.
