Structure-adaptive evaluation of additive noise level in images

Palenichka R. M., Ivasenko I. B.

Machine Graphics and Vision

1998

Vol. 7, No. 1/2

281-290

In the presented paper the problem of noise estimation is considered. The distinctive feature of the presented structural image model is the separate modeling of the object's planar shape as well as the image intensity function which is defined within the support regions of objects and for the background itself. For the intensity function model of the original image a piecewise polynominal model is assumed.
