Validation of the pcond Visibility Matching Tone Mapping Operator Comparing Subjective Responses to Computer Simulated Images and Scale-model Environments
ثبت نشده
چکیده
Human subject studies are performed to validate and refine the general-purpose luminance to brightness (tone) mapping algorithm of a software program called pcond. Through survey questionnaires, subjects compare a rendered image displayed on a video monitor with a scale-model representation of an identical space incorporating the full dynamic range of the luminous environment typical of office spaces. A validated tone mapping operator enhances the reliability and repeatability of computer-based simulation and visualization technologies thereby improving the building industry's ability to predict the visual impact of proposed architectural projects. Applications relevant to this study range from daylighting in office environments to nighttime lighting of bridges and building facades. Secondary applications include height dynamic range photography, video game design, and general-purpose renderings for animations, film, and movie production.

Assessment of the Visual Quality of Tone-mapped Images for Visibility Experiments
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 “tonemapping” operator, and the question arises whether tampering with the visual cue will not alter visual performance, p...
متن کاملReproducing 3D Prints on Monitor by Relative-Glossiness Matching Technique
For over 3 decades, computer graphics technology has been developed to simulate physically accurate image of real scene. Meanwhile, useful tone mapping methods have been developed to map luminance range of the simulated image into that of usual monitor without perceptual distortion. However, it is difficult to reproduce accurate glossiness of real objects within the limited monitor luminance ra...
متن کاملObjective Quality Assessment and Optimization for High Dynamic Range Image Tone Mapping
Tone mapping operators aim to compress high dynamic range (HDR) images to low dynamic range ones so as to visualize HDR images on standard displays. Most existing works were demonstrated on specific examples without being thoroughly tested on wellestablished and subject-validated image quality assessment models. A recent tone mapped image quality index (TMQI) made the first attempt on objective...
