Witryna8 lip 2024 · Since filtering is a major means of image processing, a large number of spatial filters have been applied to image denoising [9,10,11,12,13,14,15,16,17,18,19], which can be further classified into two types: linear filters and non-linear filters. WitrynaFor the degradation image model theory and the Wiener filter theory you can refer to the tutorial @ref tutorial_out_of_focus_deblur_filter "Out-of-focus Deblur Filter". On this page only a linear motion blur distortion is considered. The motion blur image on this page is a real world image. The blur was caused by a moving subject.
