摘要
基于干涉多光谱图像成像原理和特点,提出一种干涉多光谱图像无损压缩算法。在压缩编码时,应充分利用图像的列相关性,采用基于列的比特平面编码和游程编码,对多光谱图像进行无损压缩,特别适于低分辨率的多光谱图像压缩。目前无损压缩算法的压缩比基本在1.6～2.4之间,本算法的压缩倍数一般可达到2倍以上,并且具有良好的抗误码性能。
According to the imaging principle and characteristic of the interference multispectral images,a lossless compression algorithm for interference multispectral images is presented.During image compression,a bitplane coding and run-length coding based on columns are adopted to perform lossless compression for multispectral image by making full use of the column correlation of an image,which is especially suitable for low resolution multispectral image compresion.The compression ratio of the algorithm can reach more than 2 times.It has a good performance of error resilience.
