Recent advances have shown that learning regularization is a powerful tool to obtain customized regularizers for many low-level vision applications. In this presentation, we show our latest results on extending the Fields of Experts regularization model by deepening this structure using a series of convolutional and deconvolutional operators. The aim is to regularize not only low-level features but also mid- to high-level features to increase the reconstruction performance for medical imaging.
