This communication deals with the analysis of an image representing a finite sum of two dimensional sinewaves or complex exponentials in presence of a stationary white noise. The purpose is the estimation of the characteristics of these sinewaves (bidimensional frequency and complex amplitude). This estimation is based on the Prony Pisarenko method and requires a bidimensional extension of this approach. Then the estimated sinewaves are generated in using a recursive (autoregressive) model.
