dc.description.abstractDigital photography and videography have become ubiquitous. With ever-cheaper and more capable cameras, found in dedicated devices and, increasingly, in multipurpose smartphones and tablets, it is now easier than ever for the casual user to generate their own dense stream of personal multimedia data. With popular photo and video sharing sites, like Flickr, Facebook, and YouTube, users can share their images and video with the world, making for a vast amount of multimedia data stored at home and on the web. This flood of data presents many challenges, particularly for the non-professional, to manage their data, for example, to apply simple photographic adjustments, or to find interesting shots worth keeping among megabytes of data from even a short weekend trip. At the same time, researchers have a unique opportunity to exploit the vast amount of publicly available multimedia data to make graphics tasks easier for the individual. This dissertation presents work that seeks to address some of these challenges, and, where possible, exploit existing data sets to do so. First, we discuss a general approach that finds images similar to a given input from among a collection of photographs, from which various task-specific properties are transferred to the input. We demonstrate this basic approach in two distinct settings–image restoration and CG image enhancement. Next, we focus on collections of video. We first present a method for efficiently browsing and summarizing collections of related videos. Our approach is based on a simple pairwise video alignment that identifies a relevant sequence of video clips that best matches an input video. Finally, we discuss our work on replacing facial performances in video that requires no special hardware and can be used to retarget existing footage to synthesize new performances.en_US
