There's many old videos on media.ccc.de with very low quality, standard definition camcorder and without slide capture or at maximum grainy vga captured slides. Might it be possible to take re-render those to FHD or even 4K with everything upscaled and the projector replaced? Would need some additional magic to recognize laser pointers, mouse pointers and the presenter walking in front of the screen, but might be worth it for some of the more timeless talks.
- Gehinnn 5y agoThe tool does not work very well on very low quality videos (maybe ORB is not the best feature extractor for that). However, theoretically, it should work. The tool already calculates a projection of the pdf slide into the video frame to compare the similarity. It should be relatively easy to dump all those updated frames into a new video. Detecting laser/mouse pointers is a different story though.
