Advanced luminance control and black offset correction for multi-projector display systems Zietlow Timon Heinz Marcel Brunnett Guido In order to display a homogeneous image using multiple projectors, differences in the projected intensities must be compensated. In this paper, we present novel approaches to combine and extend existing techniques for edge blending and luminance harmonization to achieve a detailed luminance control. Furthermore, we apply techniques for improving the contrast ratio of multi-segmented displays also to the black offset correction. We also present a simple scheme to involve the displayed context in the correction process to dynamically improve the contrast in brighter images. In addition, we present a metric to evaluate the different methods and their influence on the visual quality. black offset contrast sensitivity edge blending luminance control multi-projector display perceptual seamlesness photometrical calibration tiled display 004 periodical academic journal Journal of Virtual Reality and Broadcasting 12(2015) 4 2016 1860-2037 urn:nbn:de:0009-6-42782 10.20385/1860-2037/12.2015.4 http://nbn-resolving.de/urn:nbn:de:0009-6-42782 zietlow2016
