Abstract

This paper presents the results of an initiative to transmit imagery content through a Link-16 tactical network using a multirresolution approach based on wavelets to compress images [1]. Firstly, we identify the operational requirements. Secondly, we justify why JPEG2000 is our choice for coding still images. Thirdly, we propose a method to map the JPEG2000 code-stream into Link-16 free-text messages. We propose to send the most important part of the JPEG2000 compressed image in a more error resistant Link-16 packed structure and the remaining of the image in less robust data structures but at higher data rates. Finally, we present our results based on software simulations and laboratory tests with real Link-16 terminals including a comparative analysis with Link-16 enhance throughput. A configuration using two MIDS-LVTs has being set up, along with JPEG2000 coding and decoding software tools
战术数据链上图像传输的新方案。一个案例研究:在Link-16网络中传输的JPEG2000压缩图像。方法与结果
本文介绍了一项通过Link-16战术网络传输图像内容的倡议的结果,该网络使用基于小波的多分辨率方法压缩图像[1]。首先,我们确定操作需求。其次,我们证明了为什么JPEG2000是我们编码静态图像的选择。第三,我们提出了一种将JPEG2000码流映射到Link-16自由文本消息的方法。我们建议将JPEG2000压缩图像的最重要部分以更抗错误的Link-16封装结构发送,而将图像的其余部分以较低鲁棒性的数据结构发送,但以更高的数据速率发送。最后,我们给出了基于软件仿真和真实Link-16终端的实验室测试结果,包括与Link-16增强吞吐量的比较分析。已经设置了使用两个mid - lvt的配置,以及JPEG2000编码和解码软件工具
