摘要
针对舰船网络视频图像在无损压缩传输过程中受到无损压缩系数的影响,以缩短舰船网络视频图像的无损压缩传输延时为目的,提出了舰船网络视频图像无损压缩传输优化方法研究。采用彩色分块处理技术分块处理对舰船网络视频图像,提高舰船网络视频图像的传输速度,将舰船网络视频图像的无损压缩任务分配给其他节点,解决舰船网络视频图像在能量受限节点处的无损压缩传输能力的不足,提取了网络视频图像无损压缩传输准确性,通过舰船网络视频图像无损压缩传输优化流程设计,实现了舰船网络视频图像无损压缩的传输优化。实验测试结果表明,提出的舰船网络视频图像无损压缩传输优化方法当无损压缩系数为50%、舰船网络视频的大小为1 024×20时,舰船网络视频图像的无损压缩传输延时最短。
In view of the influence of lossless compression coefficient on the ship network video image in the process of lossless compression transmission, in order to shorten the transmission delay of the ship network video image lossless compression, the optimization method of the ship network video image lossless compression transmission is proposed. In order to improve the transmission speed of ship network video image, the lossless compression task of ship network video image is assigned to other nodes to solve the shortage of lossless compression transmission ability of ship network video image at energy limited nodes, and the accuracy of network video image lossless compression transmission is extracted The optimization process design of lossless compression transmission of ship network video image realizes the transmission optimization of ship network video image lossless compression. Experimental results show that when the lossless compression coefficient is 50% and the size of ship network video is 1 024 × 20, the transmission delay of lossless compression transmission of ship network video image is the shortest.
