De-blurring using Weiner filter: De-blurring using a Weiner filter is performed by deconvolution of an image using the Weiner filter algorithm. This algorithm minimizes the mean square error between the estimated and the true images. It requires some information about the additive noise. It helps in reducing the image along with de-blurring. De-blurring using regularized filter: De-blurring using a regularized filter can be performed when there is no information about the additive noise. The results for this technique can be refined through the use of constrained parameters that control the deconvolution process.
