| 摘 要： | 对SPOT遥感图象的信息保持型压缩编码进行了研究。对几种不同的预测器及A_2、A_3线性码进行了比较,得出如下结论:在SPOT 遥感图象的信息保持型压缩编码中,采用文献1]提出的三点预测器较好,线性码采用A_3码较好;两者结合,在信息保持率大于99%时,可使压缩比达2倍以上。文内还对在压缩图象的传输与恢复中碰到的问题进行了探讨。

| Abstract: | The purpose of this paper is to study the information-preserving
compression coding of SPOT remote-sensing image.We come to the conclu-
sion.For the compression coding of information-preserving of SPOT remo-
te-sensing image,the compression ratio is larger than 2 when combining
the three-point predictor and the A_3 linear code under the condition of that
the ration of information-preserving is more than 99%. |
