Abstract :
A nonlinear subband decomposition scheme with perfect reconstruction is proposed for lossless and progressive coding of multispectral images. Such a new scheme has the merit of exploiting efficiently the spatial and the spectral redundancies contained in the multispectral images, related to a same scene. Besides, it is suitable for telebrowsing applications. Simulation tests performed on SPOT allow to assess its performances
