Samenvatting
Video processing applications such as picture rate
conversion depend on accurate and consistent motion estimation.
Most motion estimation and optical flow algorithms use some
form of spatial regularization to improve consistency, but few
perform a temporal regularization based on the symmetry
between successive vector fields. Methods that do improve temporal
symmetry are often computationally complex. This paper
describes a simple implementation of symmetry constraints in a
real-time block matching motion estimation algorithm and shows
the effect on related occlusion detection methods that are based
on forward-backward consistency checks.
