Abstract
A method comprising: receiving a high frame rate video stream of a scene, wherein the scene comprises at least one object in motion relative to an imaging device acquiring the video stream; continuously dividing, in real time, the video stream into at least one consecutive sequences of n frames each; with respect to each current sequence: (i) estimating pixel motion between at least some pairs of frames in the sequence, (ii) calculating a motion vector field for each pixel in the sequence, (iii) generating a representative frame which co-locates all of the pixels to respective pixel positions, based on the calculated motion vector fields, and (iv) aggregating, for each of the respective pixel positions, pixel values from all frames in the sequence; and outputting, in real time, a stream of the representative frames, wherein the stream has a lower frame rate than the high frame rate.
