| 摘 要： | 航空侦察图像原始数据量非常大,在实时回传的过程中必须进行压缩。在对图像进行有损或无损压缩时,无损压缩算法是必要的。本文研究了算术编码在系统中的应用,提出一种混合进制的算术编码,提高编码效率的同时增强了系统的抗误码扩散能力。试验验结果表明该算法明显优于单一进制的编码算法。 |
| 关 键 词： | 图像压缩 混合进制 算术编码 |

| Abstract: | The original data quantity of aviation scout images is very large,it's necessary to be compressed before back-transmitting.The lossless compression algorithm is needed in not only lossy but also lossless image compression.The application of arithmetic coding in the system is researched,a kind of arithmetic coding adopting mixed-notations is presented firstly,the efficiency of coding is enhanced and the antidiffusivity of error code is strengthened.The experimental results show that the algorithm has a better performance than one of single-notation. |
| Keywords: | image compress mixed-notation arithmetic coding |
