A modified inter-band scheme based on the predictors used by lossless JPEG is proposed for lossless data compression of multispectral images. Basically, the value of the current pixel in the current band is predicted by the best JPEG predictor on the previously encoded band. Improvements are achieved by considering also the corresponding prediction error on the previous band. Coding performances, assessed on a variety of Landsat TM data, are better by about 3% than those of the basic inter-band scheme, and by 7% than those attained by lossless JPEG.

Abstract

A modified inter-band scheme based on the predictors used by lossless JPEG is proposed for lossless data compression of multispectral images. Basically, the value of the current pixel in the current band is predicted by the best JPEG predictor on the previously encoded band. Improvements are achieved by considering also the corresponding prediction error on the previous band. Coding performances, assessed on a variety of Landsat TM data, are better by about 3% than those of the basic inter-band scheme, and by 7% than those attained by lossless JPEG.
