T HE human visual system is less sensitive to flickering details than to
large-area flicker. Television displays apply interlacing to profit from
this fact, while broadcast formats were originally defined to match the display

then de-interlacing, the topic of our book, is the reverse operation
aiming at the removal of the sub-sampling artefacts....
