how our flow scheme can be improved to possibly handle more complex motion in
Sec. 3.4.
The sequence
Boat
(320
306 cutout) taken from another PAL DVD has an
even faster pan than
Control Panel
and object motion as well. The motion is
very stuttering when the 25 fps input sequence is played back (
Boat25fps.avi
from [32]) and
Boat
has the most unnatural motion of all the sequences we have
run tests on. Again the frame averaging result is of poor quality as seen in Fig 6(b)
and the video (
BoatFrameAv50fps.avi
), and again the two variational TSR
schemes produce high quality results, only slightly smoothed (Figs. 6(c) and 6(d))
but with natural motion portrayal as seen in the videos. Repeated watching of the
