Abstract : Since several decades satellites have been launched for the observation of the atmosphere and the ocean. They provide sequences of photographic images. These sequences of images contain information about the dynamics of the observed systems. We present an extension of the data assimilation techniques targeted to the assimilation of image sequences in geophysics. It relies mainly upon the definition of new observation operators that allow to compare model output with information extracted from the images.
