Via email, I got a link to this remarkable (if academic) video demonstrating a series of Photoshop-esque effects as applied to video. It’s from a group at the University of Washington–here’s a blurb from the accompanying paper:
We present a framework for automatically enhancing videos of a static scene using a few photographs of the same scene. For example, our system can transfer photographic qualities such as high resolution, high dynamic range and better lighting from the photographs to the video. Additionally, the user can quickly modify the video by editing only a few still images of the scene.
If you watch to the end, you’ll see how they remove an irksome No Parking sign by cutting it out of a single video frame. It’s pretty cool.
