Abstract
We propose a restoration fixed chosen noise restoration (FCNR) taking into account together the noise instrument and the DCT compression noise of SPOT5 THR images. The coloration and the non-stationarity of the noise is managed by working in the wavelet packet coefficient space. The restoration is a lossless information process. The dimension of the SPOT5 THR images is 24000 × 24000 and the complexity of the calculation of FCNR is 700 operations per pixel.
