Blind Poissonian Image Deblurring Regularized by a Denoiser Constraint and Deep Image Prior

الملخص EN

The denoising and deblurring of Poisson images are opposite inverse problems.

Single image deblurring methods are sensitive to image noise.

A single noise filter can effectively remove noise in advance, but it also damages blurred information.

To simultaneously solve the denoising and deblurring of Poissonian images better, we learn the implicit deep image prior from a single degraded image and use the denoiser as a regularization term to constrain the latent clear image.

Combined with the explicit L0 regularization prior of the image, the denoising and deblurring model of the Poisson image is established.

Then, the split Bregman iteration strategy is used to optimize the point spread function estimation and latent clear image estimation.

The experimental results demonstrate that the proposed method achieves good restoration results on a series of simulated and real blurred images with Poisson noise.
