On-Line Recognition of Fragments of Standard Images Distorted by Non-linear Devices and with a Presence of an Additive Impulse Interference

On the base of the first-order disproportion functions, an algorithm recognizing fragments of standard images under conditions when the analyzed signal contains these fragments in a distorted form due to passing through a nonlinear device, the static characteristic of which can be represented by a polynomial with unknown coefficients, is developed. Both, continuous signals and those, described by discrete pixel brightness values of a video image, are considered with the presence of additive impulse noises.
