In a few days the Fair Siggraph 2015 begins, will be presented on the back pioneering techniques in image processing. We have some of the most interesting research that deal with the manipulation / enhancement of video closer looked at us and they are present in the coming days. First, a developed by Disney Research fairly universal algorithm that can just as well be used to oppress to noise in videos as caused by LED lights flicker, compression artifacts or movements remove blur caused and Super Resolution to calculate images. As source serve simple, filmed from the hand, compressed camcorder videos. VY = o8tJozrtMvk AnotherApplication example is the disappearance of objects from a scene, such as Raindrops or large objects, such as people using 3D mask - a shaky camera recording does not interfere. Another interesting application: a virtual aperture by which certain image planes afterwards can be brought into focus or blurred - which also has a synthetic Focus Pull possible. And Trick Shots, in which movement remain the shadow of a person in spite of camera movement at exactly the right position. PIC 1: Motion shadow The method is based on the fact that in spite of the video camera movement many image information due to the rapid image sequence occur multiple times and uses these comparison images for analysis ofImage space and the determination of the depth of the image different screen objects. Based on this data then can be quite intelligent various image manipulations such as those made above - that run via parallelization wonderfully on the graphics card and are therefore to accomplish on normal desktop computers. Who wants to know more, here are the original research paper "Sampling Based Scene-Space Video Processing". Already presented we had already developed by a team of researchers from the University of Washington and Google Lapse algorithm that shot from a variety of over a period of a tourist attraction pictures http: //www.slashcamde / news / single / Auto-lapse recordings-from-Touristenphot-12136.html (automatically lapse video) created. The path from research to finished tool has accelerated in recent years and no longer must have the manufacturer of video editing programs (such as Adobe) Pass - Microsoft's Super-lapse tool Hyperlapse is for example already http: //www.slashcam .com / news / single / Intelligent-lapse Microsoft Hyperlapse-jetz-12249.html Available (as a free app). Here to set the mood for the next Siggraph news the Demoreel Siggraph 2015: VY = XrYkEhs2FdA. u003cimg src=
