Gradient based motion estimation |
摘要 |
A technique for generating motion vectors for applications requiring field frame rate interpolation e.g.standards conversion. The image gradients are calculated on the same standard as the input video or film signal and then vertical/temporal interpolators 20 are used to convert to the output standard before determining the motion vectors. This allows motion vectors to be easily calculated on the output standard. |
