Paper Abstract

We study the ability to derive meaningful information from decompressed imaging spectrometer data. Each hyperspectral band is linearly predicted by a previously transmitted band. The residual, formed by subtracting the prediction from the original data is compressed either with a near-lossless bit plane coder or with the lossy JPEG2000 algorithm. We investigate the effects of these two compression methods on hyperspectral image processing using whole- and mixed-pixel analysis techniques. Surprisingly, the lossy coder outperforms near-lossless method in terms of its impact on final hyperspectral data applications.
