Fast Local Tone Mapping, Summed-Area Tables and Mesopic Vision Simulation
High dynamic range (HDR) imaging is becoming an increasingly popular practice in computer graphics, bringing unprecedented levels of realism to computer-generated imagery and rich detail preservation to photographs and films. HDR imagery can embrace more accurately the wide range of light intensities found in real scenes than its counterpart, low dynamic range (LDR), which are tailored to the l...
متن کاملA Retargeting Approach for Mesopic Vision: Simulation and Compensation
Retargeting approaches aim at providing a unified framework for image rendering in which both the intended scene luminance and the actual luminance of the display are taken into account. At the core of any color retargeting method, a color vision model and its inverse are employed. Such a color appearance model should be invertible and cover the entire luminance range of the human visual system...
متن کاملTone Reproduction for Interactive Walkthroughs
When a rendering algorithm has created a pixel array of radiance values the task of producing an image is not yet completed. In fact, to visualize the result the radiance values still have to be mapped to luminances, which can be reproduced by the used display. This step is performed with the help of tone reproduction operators. These tools have mainly been applied to still images, but of cours...
متن کاملColor Correction for Tone Reproduction
High dynamic range images require tone reproduction to match the range of values to the capabilities of the display. For computational reasons as well as absence of fully calibrated imagery, rudimentary color reproduction is often added as a postprocessing step rather than integrated into the tone reproduction algorithm. However, in the general case this currently requires manual parameter tuni...
متن کاملRod and Cone Contributions to Mesopic Vision
Mesopic light levels span approximately 3-4 log units in the natural viewing environment, including many indoor lighting settings, and most twilight or nighttime outdoor and traffic lighting environments. Traditional studies of the contribution of the different photoreceptor types to mesopic vision have been hampered by an inability to modulate the rod or cone systems independently. Our approac...
