Bi-directionally interpolated frame using conventional method.
For the sake of comparison to the block-based conventional methods, Fig. 15
shows the resulting middle frame interpolated using a conventional FRUC algo-
rithm that utilizes bi-directional motion estimation, [8], with hexagonal search pat-
tern [15]. It is clear that our approach interpolates visually more pleasant frames
without blocking artifacts at object boundaries.
