摘要
本文研究了遥感图象,利用其波段间的相关性进行三维自适应预测编码。使它的熵值比波段内的固定系数预测编码下降0.4比特/象素,平均压缩比有可能从2提高到2.5以上。
In this paper, the remote sensing imagery is studied, and howto do 3-dimension adaptive predictive coding is discussed using correlation ofMSS imagery between multispectral bands. The entropy has been reduced 0.4 bitper pixel than the predictive coding of fixed coefficients in the bands. Theaverage compressive rate may be rise 2.5 times high, and also doesn't loss anyinformation.
