Abstract
This paper considers the aspects of robust M-estimation in regularized image restoration. Robust functionals are employed to allow the representation and efficient suppression of a wide variety of noise processes and permit the reconstruction of sharp edges. A new class of robust entropic functionals is introduced, which operates only on the high-frequency content of the signal and reflects sharp deviations in the signal distribution. This class can also incorporate prior structural information regarding the original image, in a way similar to the maximum information principle. The properties of robust algorithms are demonstrated through restoration examples in different noise environments.
