Modern video cameras often only capture a single color per pixel in a single pass operation. This process is called ltering, where pixels are ltered through a color lter array, and the Bayer lter is perhaps the most common lter used today. This means that the missing color channels must be restored in the image or the video frame in a post-processing step, i.e., a process referred to as debayering. In a live video scenario, this operation must be performed eciently in order to output each video frame in real-time, while also yielding acceptable visual quality. Here, the authors evaluate debayering algorithms implemented on a GPU for real-time panoramic video recordings using multiple 2K-resolution cameras.<\/p>","DOI":"10.4018\/ijmdem.2015070101","type":"journal-article","created":{"date-parts":[[2015,6,29]],"date-time":"2015-06-29T20:32:25Z","timestamp":1435609945000},"page":"1-16","source":"Crossref","is-referenced-by-count":1,"title":["An Experimental Evaluation of Debayering Algorithms on GPUs for Recording Panoramic Video in Real-Time"],"prefix":"10.4018","volume":"6","author":[{"given":"Ragnar","family":"Langseth","sequence":"first","affiliation":[{"name":"ForzaSys AS, Oslo, Norway"}]},{"given":"Vamsidhar Reddy","family":"Gaddam","sequence":"additional","affiliation":[{"name":"University of Oslo and Simula Research Laboratory, Oslo, Norway"}]},{"given":"H\u00e5kon Kvale","family":"Stensland","sequence":"additional","affiliation":[{"name":"University of Oslo and Simula Research Laboratory, Oslo, Norway"}]},{"given":"Carsten","family":"Griwodz","sequence":"additional","affiliation":[{"name":"Simula Research Laboratory, Oslo, Norway"}]},{"given":"P\u00e5l","family":"Halvorsen","sequence":"additional","affiliation":[{"name":"University of Oslo and Simula Research Laboratory, Oslo, Norway"}]},{"given":"Dag","family":"Johansen","sequence":"additional","affiliation":[{"name":"Univeristy of Troms\u00f8 - The Arctic University of Norway, Troms\u00f8, Norway"}]}],"member":"2432","reference":[{"key":"ijmdem.2015070101-0","doi-asserted-by":"publisher","DOI":"10.1109\/ICIP.1998.723540"},{"key":"ijmdem.2015070101-1","unstructured":"Bayer, B.
