Abstract
The invention relates to a method and a device for processing a mosaic of noisy source images exhibiting overlap zones where at least two of the source images are superimposed. According to the invention, the method comprises a step of generating a random noise (35) in the overlap zones so as to compensate at least partially for the deviation in noise between the overlap zones and the zones where the source images are not superimposed, called non-overlap zones.

Method of processing a mosaic of noisy source images exhibiting overlap zones where at least two of the said source images are superimposed, wherein it comprises a step of generating a random noise in the overlap zones so as to compensate at least partially for the deviation in noise between the overlap zones and the zones where the source images are not superimposed, called non-overlap zones.
Device for processing a mosaic of noisy source images exhibiting overlap zones where at least two of the said source images are superimposed, comprising means for generating the said mosaic, wherein it furthermore comprises:
- means for estimating statistical parameters of a random noise in the overlap zones and in the zones where the source images are not superimposed, called non-overlap zones, and
- means for generating a random noise in the overlap zones on the basis of said statistical parameters.
