"The paper deals with influence of the 2D sampling process upon image quality. The Optical Transfer Function (OTF), which is closely related to the Point Spread Function (PSF) of optical and electro-optical imaging systems, can be regarded as an objective measure of their quality. The main goal was the implementation of direct and blind deconvolution methods in MATLAB environment, in order to estimate these parameters and use them for computation of other characteristics, such as the Modulation Transfer Function (MTF) and the Phase Transfer Function (PTF)."@en . . .
