Abstract

Independent component analysis has been known for its success in blind source separation. It features a decorrelation capability beyond second-order moments. Recently ICA has been used in lossy compression for target detection in hyperspectral imager data where loss of unimportant features does not affect the detection result. For the ultraspectral sounder data, it is better to be lossless compressed for the ill-posed retrieval of geophysical parameters. In this paper we will try to use ICA in the lossless compression of ultraspectral sounder data. The compression result shows that ICA compares favorably with JPEG2000, JPEG-LS, and CCSDS IDC 5/3 on the ten standard AIRS granules dataset.
