Abstract :
The article mainly deals with the error correction in multispectral remote sensed images transmitted from satellite to the ground by digital channels. The basic idea is to use the knowledge of the other bands to correct the errors present in one band. It is possible to find out a relationship between pixels close to each other, and in this way there is a certain degree of correlation within pixels belonging to the same band in a close neighbourhood. The coefficients of this relationship are, in turn, quite probably, similar to the ones calculated in one of the other bands
