An encoding system encodes and decodes video data using an exposed area
fill processor. A nonkey frame is encoded as a set of kinetic information
relating segments of a reference frame to the nonkey frame and the nonkey
frame is decoded from segments of at least one reference frame, the
kinetic information and results of an exposed area fill process that
estimates contents of the nonkey frame not already covered by the
segments and the kinetic information. The exposed area fill results can
be determined at the encoder and conveyed to the decoder or the decoder
can determine the results independently. The encoded video data can
include an indication of which of a plurality of fill schemes are used,
or the decoder can determine the indication by itself. The exposed area
fill information might include bounds of areas to be filled and/or pixel
values of pixels therein.
