Abstract
Popular techniques employed to code the Dis#
placed Frame Di#erence #DFD# treat it no di#er#
ently from an ordinary image for coding purposes.
Since the DFD is generated by the process of mo#
tion compensation# such methods do not fully ex#
ploit the underlying redundancies. This paper is
aimed at proposing a DFD coding method which
exploits such redundancies while incurring neg#
ligible information overhead. The key idea is to
predict locations of high DFD concentration which
occupy small portions of the image and use this
predicted information #which is also available to
the decoder with out additional information trans#
