Summary
FRUC is an important problem for consumer electronics, especially for improving
the performance of hold-type panel displays. Increasing frame-rates on typical me-
dia content, which often involves dynamic scenes, requires modeling and utilization
of motion field more precisely.
In this chapter, first an overview of the conventional FRUC algorithms that
mainly utilize block-based motion estimation and compensation with translational
motion model is provided. In order to avoid several shortcomings of conventional
methods such as blocking artifacts and failure to robustly model correct object mo-
tion, two region-based FRUC techniques utilizing 2D planar perspective and 3D
rigid body motion models are presented. Both methods rely on the idea of perform-
ing the motion interpolation step in the parameter space of the original 3D motion
and structure elements of the scene. Experimental results show that both methods
yield visually pleasing results without halo effects on dynamic scenes.
