Abstract:The quality of photographs is often reduced by sensor noise. This was a problem with film cameras, and is still a problem with current CCD and CMOS sensors, particularly in low-lighting conditions. De-noising techniques do not always perform satisfactorily. Typical de-noise techniques reduce the sharpness of the image. In this paper we propose a new de-noising technique, which is based on a dual-shot technique. The proposed algorithm is based on selectively removing high frequencies that do not correlate well … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
