Video
coding enables a trade-off between the
bitrate
and the quality, and hence efficient storage
and transmission of video. Interpolation problems
arise naturally in the context of video coding,
because the true displacements of objects from one
frame to another are independent of the sampling
grid of cameras. Therefore, in motion-compensated
prediction, fractional-sample accuracy is used to
more accurately capture continuous motion. The
focus of this book is to develop high quality inter¬
polation techniques, suitable for video coding and
image processing. |
