Gaussian Noise In DIP (CSE)

Gaussian Noise:  Because of its mathematical tractability in both the spatial and frequency domains, Gaussian (also called normal) noise models are used frequently in practice.   In fact, this tractability is so convenient that it often result. Gaussian models being used in situation in which they are marginally applicable at best.   The PDF of … Read more

Degradation And Restoration In Digital Image Processing

Image Degradation And Restoration Model :-  As fig. show, that degradation process is modeled as a degradation function that, together with an additive noise term, Operates on an input Image f(x,y), to produce a degraded image g(x,y), some knowledge about the degradation function H and some knowledge about the additive noise term n(x,y), the objective of restoration is … Read more

Introduction Of Image Restoration

Image Restoration :-  Image restoration is the operation of tating a corrupt/noise image and estimating the clean original image. Corruption may come in many forms such as motion blur, noise and camara mis focus. Image restoration is performed by revirsing by the process that blurred the image and such is performed by imaging a point … Read more
