| Abstract: | The dynamic masking in the synthesis between the virtual computer image sequence of architecture scheme and the real environmental image sequence has been investigated where the segmentation edge varies with time. A keyframe based interpolation algorithm of dynamic masking by tracking the segmentation edge of foreground with closed B spline and rules for judging the motion keyframe of sample point on the segmentation spline are put forward. The experimental result shows that the algorithm is valid and viable for the application in practice. |
