Model

Acquisition model: input = alpha x Poisson(H x original/alpha) + Gaussian(0, nsigma^2);

Point-spread function (PSF): H

Noise levels:

  • alpha : scaling factor of Poisson noise
  • nsigma: noise std of additive Gaussian noise

Usage

This version implements the PURE-LET non-blind deconvolution algorithm, both the image and PSF data are needed.

Example:

directly run 'demo.m' (more details inside)
