Experimental comparison of tone mapping operators using a visual performance index
Computer graphics provide a powerful tool to study lighting and visual signalling as well as information requirements of transport and traffic, through psycho-visual experiments. However, real-world luminance dynamic range is often too high for display devices. Compression must be achieved using a so-called tone-mapping operator (TWO), 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 the recent years, a lot of work was done in the Computer Graphics (CG) community in order to achieve a high quality display of complex images. However, the main issue in terms of image quality was the global appearance of displayed images, which leads to visual appearance image quality indexes. In this paper, we propose a visual performance image quality index, devoted to road vision applications which mainly concern CIE Division 4 issues. Our index allowed us to compare five TMOs from the CG literature, for three critical driving situations (daytime in fog, night-time with and without on-coming headlamps in the field of view).
