Abstract :
The problem of nonlinear distortions of images reconstructed from incomplete and noisy spectrum data using nonlinear optimization methods such as the maximum entropy method is considered. To decrease the level of nonlinear distortions it is proposed to seek a solution in the space of complex functions using the generalized maximum entropy method instead of classical one
