This was made by resampling in time with a DCT. Problems with this: 1. practically, it needs the entire movie in memory. 2. gibbs phenomenon in time is really weird. These could both be addressed by using short overlapping windows, and then the process becomes just like typical sinc/lanczos interpolation in time.
- mistercow 14y agoWell, yes, you can interpolate in the frequency domain like that, which works pretty well for resampling 2D data as well. However, it does not transition shapes from location to location; instead, it looks like one frame is fading into another. What's fascinating about this multiscale algorithm is that it appears to actually exaggerate the motions rather than merely increasing the contrast of the changes.
