Abstract:
1. A method for processing a pixel value of at least one image pixel contained in a current frame of a video sequence, said method comprising the steps of constructing an individual motion trajectory comprising 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, wherein said step of constructing said individual motion trajectory comprises the steps of: wherein 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 per frame, a first motion-shifted version of said at least two motion-shifted versions per frame being determined based on a first motion model and a second motion-shifted version of said at least two motion-shifted versions per frame being determined based on a second motion model, wherein the second motion model provides a more accurate estimation of pixel motion than the first motion model, wherein for each of the plurality of preceding and/or subsequent frames, the distance between said at least two motion-shifted versions in their respective same frame is determined, wherein, for each of the plurality of preceding and/or subsequent frames, one of said at least two motion-shifted versions of the at least one image pixel is selected per frame based on the distance or distances between the motion-shifted versions in their respective same frame, and wherein the selected motion-shifted version is added to the individual motion trajectory.
