An iterative blind image restoration algorithm based on self-deconvolution and incremental Wiener filter (SDIWF-IBD) is purposed. The self-deconvolution method for PSF estimation is applied to IBD to extract the Fourier estimation of PSF exactly. To keep algorithm convergence steady
incremental Wiener filter is used in image estimation step of IBD. Furthermore
in-iterative acceleration is suggested to control the speed of algorithm convergence and reduce total external iteration. Experimental results indicate that
more detail is recovered in restoration image with few distortions
and algorithm converges to a small error quickly. So
the SDIWF-IBD algorithm has good restoration ability in fast and controllable convergency speed
