ABSTRACT:
A method of temporally adaptive filtering of the frames of an image sequence is disclosed. To filter the kth frame, first, the motion trajectories that transverse the pixel locations at the kth frame are determined using a motion estimation algorithm. Motion trajectories pass through a predetermined number of frames neighboring the kth frame. Image values at the neighboring frames, along motion trajectories are then evaluated. Temporally adaptive linear minimum mean square error (LMMSE) estimates of the image values at the pixel locations of the kth frame are determined using the image values along the motion trajectories. These steps are repeated for each of the other frames of the image sequence.
