Validation of Digital Image Representations of Low-Illumination Scenes 2006-01-1288

The purpose of this paper is to present an updated methodology for validating the visibility of objects in low-illumination digital photographs. A procedure is presented for creating prints from digital images that accurately represent the observers' view at a low-illumination scene. In addition, procedures are presented that allow representative displays of digital images on CRT and projector devices. The results indicate that the selected luminance settings of experimenters closely matched the selections of test subjects viewing similar images in print form and on CRT and projector displays. Further, both between-subject and between-experimenter variability was small.
