摘要
针对星载遥感图像的无损压缩具体需求,对CCSDS建议的无损数据压缩标准进行了两方面的改进,大大提高了硬件的处理速度.实验结果表明:该方案在无损压缩编码效率和处理速度上均具有较高的性能,能满足星载遥感图像实时处理的要求.
For the application of onboard remote sensing lossless image compression, two parts of improvement to CCSDS lossless data compression are presented in this paper. The experimental results indicate that this algorithm is superior to the standard CCSDS algorithm at both lossless coding efficiency and hardware processing speed. So it meets the need of real time onboard image processing.
