| 摘 要： | 考虑到无线视频传感器网络中节点资源及能源受限等情况,针对视频监控固定视场中存在的大量冗余信息,提出了一种面向无线视频传感器网络的目标检测与视频重构方法来有效去除冗余.首先传输JPEG2000压缩的背景图像,继续采集视频图像,对其进行目标检测,将检测到的目标图像进行JPEG2000压缩,然后仅传输目标图像压缩码流及其空间...

| Abstract: | In consideration of the restrictions of node resources and energy in wireless video sensor networks,an object detection and video reconstruction method for wireless video sensor networks is proposed,aiming at elim-inatiny of the large quantity of redundant information in fixed area of view during video transmission.First of all,the background image compressed by JPEG2000 is transmitted.Then,the compressed bit-stream of object image,coupled with its space position is transmitted while image fusion and the re... |
