摘要
针对舰载无人机载图像实时传输系统的要求,提出了一套采用整数小波变换和改进嵌入式零树编码、分级压缩/解压缩的图像编码系统方案,对非感兴趣的大面积海面区域采用较高的压缩比,而对于感兴趣的目标区域采用相对较低的压缩比,这样既能大大减少数据的实时传输量,又能对目标识别等重要军事任务有很好的效果。
Aiming at the requirement for the real- dine image transmission system of shipbome UAV system, an integer wavelet transform algorithm with modified embedded zerotree wavelet coder （EZW） and graded compression / decompression is introduced to compress images. That system adopts higher compression ratio to no-intesting large sea area, and adopts relatively lower compression ratio to the interesting goal area. In this way, that system not only reduces datum amount to benefit for real - time transmission greatly, but also can achieve good results in the important military tasks such as object recognaition.
