在两类计算机上用软件实现了典型MSS数据的信息保持型的编码/解码
压缩比略大于2.本文是课题报告及后续工作的简要报导
所提出的算法与JPEG建议中有关部分相似。
The predictor:x0=1/2x1+1/4(x3’+x4’)
for the coding of television pictures (interlaced)
is also suitable lor the coding of original data of multi-spectral scanner (MSS) satellite remote sensing pictures (non-interlaced).By using such a predictor and simple entropy coding (As code)
the lossless coding/decoding is realized on two kinds of computers by softwares for typical MSS pictures
with compression ratio slightly greater than two.This paper is a brief report of a project and related works following it
wh le the proposed algorithm is very similar to the corresponding one proposed by JPEG.
