Author:Theron, Bertus; El-Desouki, M; Aljekhedab, FMR; Alayed, MSI; Alsawad, MSDDate:Apr 2013A key imaging quality metric for an optical system (e.g. a camera or surveillance device) is its resolution. Methods to measure this, range from visual observation methods on resolution target charts, through more rigorous characterization, ...Read more
Author:Duvenhage, BDate:Nov 2014The real-time super-resolution technique discussed in this paper increases the effective pixel density of an image sensor by combining consecutive image frames from a video. In surveillance, the higher pixel density lowers the Nyquist rate ...Read more
Author:Theron, BertusDate:Apr 2013The purpose of the workshop was for participants to interactively discuss (with regard to optical imaging or optical imaging systems): Local end-user needs; What those needs imply for associated new & existing laboratory testing & measurement ...Read more
