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.</p><p>Computer scientists at the University of Washington <a
href="http://grail.cs.washington.edu/projects/videoenhancement/videoEnhancement.htm">have</a> 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.</p><p>Take a look at the original images in the upper row and the enhanced images in the lower row.</p><p><img

id="more-6262"></span>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.</p><p><object

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&#215;600 frame.</p><p>A code dump of the project is available on the project&#8217;s website which might be useful as a reference for implementing the algorithm.</p> ]]></content:encoded> <wfw:commentRss>http://www.ghacks.net/2008/08/18/using-photos-to-enhance-video/feed/</wfw:commentRss> <slash:comments>5</slash:comments> </item> </channel> </rss>
