　　报告摘要：The topic of this talk is a recent paradigm for image reconstruction called the Plug-and-Play (PnP) method which has attracted lot of attention for computational imaging problems. This involves repeated inversion of the imaging (forward) model followed by ad-hoc regularization using a powerful denoiser. Surprisingly, though PnP is not derived from a statistical or variational perspective, it yields state-of-the-result in several imaging problems. In fact, the theoretical aspects of PnP, such as convergence and optimality, is not fully understood even for linear denoisers.  In this talk, we will discuss some recent progress in this direction and the open problems at this point.
