发明名称 GRADIENT BASED MOTION ESTIMATION
摘要 A technique for generating motion vectors for applications requiring field o r frame rate interpolation and especially in 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 motio n vectors to be easily calculated on the output standard.
