| Abstract | Computer graphics provides a powerful tool to study lighting and visual signalling as well as information requirements of transport and traffic. However, real-world luminance dynamic range is often too high for display devices. Compression must be achieved using a so-called tone-mapping operator, and the question arises whether tampering with the visual cue will not alter visual performance, possibly invalidating comparisons between behaviours observed in real and simulated conditions. In this paper, we present a psychometric experiment for assessing the quality of tone-mapping in terms of visual appearance and visual performance. Subjects were asked to judge on the regularity of various grey level gradations and to locate low-contrast differences, first in a reference scene and then with tone-mapped images of this scene. Four tone-mapping algorithms were tested, none of which fully s쳮ded in achieving the look and feel of the real scene. |
