Deep-URL: A Model-Aware Approach To Blind Deconvolution Based On Deep Unfolded Richardson-Lucy Network
This addresses the need for interpretable models in life-critical applications like medical imaging or autonomous systems, though it is incremental as it builds on classical methods.
The paper tackles the problem of blind deconvolution by proposing Deep-URL, an interpretable deep-learning architecture that recovers both the blur kernel and sharp image from blurred images, demonstrating significant improvement over state-of-the-art algorithms.
The lack of interpretability in current deep learning models causes serious concerns as they are extensively used for various life-critical applications. Hence, it is of paramount importance to develop interpretable deep learning models. In this paper, we consider the problem of blind deconvolution and propose a novel model-aware deep architecture that allows for the recovery of both the blur kernel and the sharp image from the blurred image. In particular, we propose the Deep Unfolded Richardson-Lucy (Deep-URL) framework -- an interpretable deep-learning architecture that can be seen as an amalgamation of classical estimation technique and deep neural network, and consequently leads to improved performance. Our numerical investigations demonstrate significant improvement compared to state-of-the-art algorithms.
