Adaptive video data frame resampling

A computer-based method to adaptively process video data, the method comprising:

• deinterlacing at least a first and a second field of an interlaced frame to form first and second frames, the first frame comprising scanlines of a first temporal instant, the second frame comprising scanlines of a second temporal instant that is different from the first temporal instant;
• independently resampling the first and second frames to form respective first and second resampled frames;
• interleaving scanlines from the first and second resampled frames to generate a resampled interlaced frame comprising at least first and second resampled fields;
• if a top and a bottom field of the resampled interlaced frame are from a same temporal instance, filtering the resampled interlaced frame with a sharp filter, and
• if a top and a bottom field of the resampled interlaced frame represent different respective temporal instances, filtering the resampled interlaced frame with a smooth filter.
