Editing Bit plane (section)

=== Video motion estimation ===

Some [[motion estimation]] algorithms can be performed using bit planes (e.g. after the application of a filter to turn salient edge features into binary values).<ref>{{cite CiteSeerX|title=bitlane motion estimation|citeseerx=10.1.1.16.1755}}</ref> This can sometimes provide a good enough approximation for correlation operations with minimal computational cost. This relies on an observation that the spatial information is more significant than the actual values. Convolutions may be reduced to [[bit shift]] and [[popcount]] operations, or performed in dedicated hardware.
