ProxiMAP enhances imaging restoration by improving MAP approximation

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced ProxiMAP, a novel iterative approximation method designed to enhance Plug-and-Play (PnP) restoration techniques in imaging inverse problems. This new approach aims to address the oversmoothing issue common with MMSE denoisers by better targeting the Maximum A Posteriori (MAP) estimate. ProxiMAP queries the denoiser at the residual noise level of the current iterate, keeping the denoiser in-distribution and improving perceptual quality in various applications like deblurring and super-resolution, sometimes at the cost of PSNR. To increase efficiency, a one-step distillation and a hybrid schedule are also proposed, retaining significant improvements at a reduced computational cost. AI

IMPACT ProxiMAP offers improved perceptual quality in image restoration tasks, potentially advancing the capabilities of AI-driven imaging applications.

    Beyond MMSE: Enhancing PnP Restoration with ProxiMAP

    arXiv:2605.16396v2 Announce Type: replace Abstract: Plug-and-Play (PnP) methods for imaging inverse problems replace the proximal operator of the prior, a maximum a posteriori (MAP) denoiser, with a pretrained minimum mean squared error (MMSE) denoiser. MMSE estimates are oversmo…
