Capability of Ophthalmology Residents to Detect Glaucoma Using High-Dynamic-Range Concept versus Color Optic Disc Photography
BACKGROUND Assessment of color disc photograph (C-DP) is affected by image quality, which decreases the ability to detect glaucoma. High-dynamic-range (HDR) imaging provides a greater range of luminosity. Therefore, the objective of this study was to evaluate the capability of ophthalmology residents to detect glaucoma using HDR-concept disc photography (HDR-DP) compared to C-DP. DESIGN Cross...
متن کاملFundus and Optic Disc Photography
l'rircuiar polarizers have been used v for difrerent ophthalmic applications, such as ophthalmoscopy,' lens photography,' and corneai endothelial microscopy.3 To the best of our knowledge, circular polarizers have not been applied to fundus photography. A linear polarizer polarizes light in a plane. In fundus photography, it has been used to show the birefringence of the nerve fiber layero and ...
متن کاملComparison of optic disc margin identified by color disc photography and high-speed ultrahigh-resolution optical coherence tomography.
OBJECTIVE To determine the correspondence between optic disc margins evaluated using disc photography (DP) and optical coherence tomography (OCT). METHODS From May 1, 2005, through November 10, 2005, 17 healthy volunteers (17 eyes) had raster scans (180 frames, 501 samplings per frame) centered on the optic disc taken with stereo-optic DP and high-speed ultrahigh-resolution OCT (hsUHR-OCT). T...
متن کاملUnbounded High Dynamic Range Photography Using a Modulo Camera Citation
This paper presents a novel framework to extend the dynamic range of images called Unbounded High Dynamic Range (UHDR) photography with a modulo camera. A modulo camera could theoretically take unbounded radiance levels by keeping only the least significant bits. We show that with limited bit depth, very high radiance levels can be recovered from a single modulus image with our newly proposed u...
متن کاملTime Lapse High Dynamic Range (HDR) Photography
In this paper, we present an approach to a pipeline for time lapse photography using conventional digital images converted to HDR (High Dynamic Range) images (rather than conventional digital or film exposures). Using this method, it is possible to capture a greater level of detail and a different look than one would get from a conventional time lapse image sequence. With HDR images properly to...
