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.
