Abstract

Processing the pixel value of at least one image pixel contained in a current frame of a video sequence includes constructing an individual motion trajectory including motion-shifted versions of the at least one image pixel over a plurality of preceding and/or subsequent frames, and processing the pixel value based on the individual motion trajectory. Constructing the individual motion trajectory includes choosing the at least one image pixel of the current frame as a start pixel of the individual motion trajectory, and adding motion-shifted versions of the at least one image pixel of preceding and/or subsequent frames to the individual motion trajectory. For each of the plurality of preceding and/or subsequent frames, at least two motion-shifted versions of the at least one image pixel are determined, and one of the at least two motion-shifted versions of the at least one image pixel is selected and added to the individual motion trajectory.
