Several techniques have been proposed in the last few years for the compression or hyperspectral and multispectral images. All of them tried to exploit, in various degrees, the particularities of these images, especially of the intraband and interband redundancies they exhibit. In this paper, the authors considered the compression of multitemporal and multispectral images and made a comparison between still image and video approaches for the compression of these images acquired by SPOT 1, 2 and 4. The still image compression is realized using the state-of-the-art JPEG2000 codec, while the video one uses an EZBC wavelet-based codec. Both spectral and temporal decorrelation approaches are discussed.
