In other words, a technology that blows me away. This time it is a new method of enhancing video by using photos of the same scene to create effects like high definition resolutions, enhanced exposure, object removal, object touchup or high dynamic range.

Computer scientists at the University of Washington have developed a software application that automatically enhances a video by using several photographs of the same scene. This takes the higher resolution and detail of photos in comparison to videos into account to deliver stunning enhanced videos.

Take a look at the original images in the upper row and the enhanced images in the lower row.

While it might be nice to see the differences on photos it is more interesting to see a video with moving pictures and a voice explaining the technique in greater detail.

The technique has a few limitations. It currently works only on static scenes, meaning scenes with no moving objects except for the camera and lighting. It furthermore takes roughly 5 minutes to compute one 800×600 frame.

A code dump of the project is available on the project’s website which might be useful as a reference for implementing the algorithm.
