Bayesian Deep Learning for Image Reconstruction: From structured sparsity to uncertainty estimation

Weisheng Dong, Jinjian Wu, Leida Li, Guangming Shi, Xin Li

Abstract: Conventional wisdom in model-based computational imaging incorporates physics-based imaging models, noise characteristics, and image priors into a unified Bayesian framework. Rapid advances in deep learning have inspired a new generation of data-driven computational imaging systems with performances even better than those of their model-based counterparts. However, the design of learning-based algorithms for computational imaging often lacks transparency, making it difficult to optimize the entire imaging system in a complete manner.
