Abstract
A method and encoding system for reducing artifacts in a digital video sequence of image frames. The method acquires a current frame of the digital video sequence, and retrieves a previous frame of the digital video sequence from a frame delay. The method applies a recursive temporal filter to the current frame and the previous frame to generate a filtered frame. The method then applies a mixer to the current frame and the filtered frame to generate an output frame. The method stores the output frame in the frame delay.
