METHOD AND DEVICE FOR PROCESSING PIXELS CONTAINED IN A VIDEO SEQUENCE

摘要

An embodiment of the present invention relates to a method for processing the pixel amplitude 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 neighboring frames, and processing the pixel amplitude based on the individual motion trajectory; wherein said step of constructing said individual motion trajectory comprises the steps of: - 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, - wherein for each motion-shifted version to be added, it is determined whether a difference value, which indicates the change of the pixel amplitude of the respective motion-shifted version between consecutive frames, is smaller than an amplitude threshold value, which is individually assigned to the current frame or a frame portion of the current frame comprising said at least one image pixel, and - wherein said step of adding further motion-shifted versions is stopped if said difference value exceeds said amplitude threshold value.
