Image restoration deals with recovering the original scene from the raw data recorded by a flawed optical device subject to systematic and random degradations. Modelled as a (convolution-) integral equation, it belongs to the class of notoriously ill-posed inverse problems characterized by their pathologic sensitivity to perturbations in the data. Casting the problem in an abstract framework of (robust) parameter estimation, we elaborate the theoretical background and discuss different regularization techniques. A selection of algorithms is reviewed and adapted for microscopy. Finally their performance is evaluated on sets of both synthetically generated and real-world data.
