Abstract
Method of eliminating interference signals from video signals by means of motion-adaptive transversal filtering, in which the motion is detected in the two-dimensional plane for the purpose of S/N ratio improvement. To this end, the forward and backward-motion signals are combined to a common motion signal and transformed into a polar coordinate signal from which the coefficients for controlling the transversal filter are derived.
