than the Endostabf2f by 0.4 decibels approximately.
This might be because of the available long trajectory
for smoothening due to steady camera which usually
not frequently available in case of endoscopic videos.
Subjective assessment of the stabilized videos is re-
quired to affirm the quality of stabilized videos as re-
quired by the user. Videos stabilized by AE contain
jumps in the frame during scene change. This is ex-
treme in case of endoscopic videos since they con-
tain very frequent scene changes. Hence, visualiza-
tion of such videos misguides the surgeon prooving
to be dangerous. Our algorithm in contrast takes these
issues into account and is customized for the purpose
of endoscopic video stabilization.
There is scope for further optimization of the En-
doStabf2f algorithm with respect to motion estima-
tion using optimized algorithms which is a part of our
ongoing research. In addition, the image composition
part could be optimized to exclude the black regions
after compensation without losing too much of impor-
tant information.
