中文摘要：
针对多媒体传感网采集图像信息的空间冗余问题,提出了一种面向数据压缩的无线多媒体传感器网络节点的选择方法.该方法从节点3维感知模型出发,设计空间相关模型以描述感知图像数据之间的相关性,在此基础上,提出基于相关性的节点选择方法,减少了采集数据的空间冗余.仿真实验结果验证了新方案的有效性.
英文摘要：
Multimedia sensor network is an advanced form of sensor networks. It has multimedia information perception,processing and transmission capacity. For the problem of great redundancy and correlation in the collection data,a node selection approach for data compression was designed. By using the correlation model based on three-dimensional perception,it describes the relevant characteristics between the observed images data. Then the camera node selection algorithms was proposed based on correlation coefficients to reduce the spatial redundancy of sensing data. A set of comparisons are performed to evaluate the effective of our algorithms.
