Fast Local Tone Mapping, Summed-Area Tables and Mesopic Vision Simulation

چکیده
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 limited intensities of display devices. Simply put in computer terminology, think of HDR as a very large, continuous range of intensities encoded in a floating-point representation (but not necessarily), while LDR translates to coarse, quantized ranges, usually encoded as 8-bit integers and thus limited to 256 discrete intensities.

Real-Time Photographic Local Tone Reproduction Using Summed-Area Tables
High dynamic range (HDR) rendering is becoming an increasingly popular technique in computer graphics. Its challenge consists in mapping the resulting images’ large range of intensities to the much narrower ones of the display devices in a way that preserves contrastive details. Local tone mapping operators effectively perform the required compression by adapting the luminance level of each pix...
متن کاملMaximum Entropy Spectral Modeling Approach to Mesopic Tone Mapping
Tone mapping algorithms should be informed by accurate color appearance models (CAM) in order that the perceptual fidelity of the rendering is maintained by the tone mapping transformations. Current tone mapping techniques, however, suffer from a lack of good color appearance models for mesopic conditions. There are only a few currently available appearance models suited to the mesopic range, n...
متن کاملFast HDR Image-Based Lighting Using Summed-Area Tables
We introduce a technique that uses summed-area tables to dynamically compute image-based lighting from highdynamic-range environment maps. A combination of first order and second order summed-area tables are used to approximate various BRDFs such as the Phong BRDF. A key feature of the approach is “offsetting” of the original image with respect to its mean, in order to significantly increase th...
متن کاملFast Summed-Area Table Generation and its Applications
We introduce a technique to rapidly generate summed-area tables using graphics hardware. Summed area tables, originally introduced by Crow, provide a way to filter arbitrarily large rectangular regions of an image in a constant amount of time. Our algorithm for generating summed-area tables, similar to a technique used in scientific computing called recursive doubling, allows the generation of ...
متن کاملA Color Appearance Model Applicable in Mesopic Vision
We propose a color vision model that can be used to predict color appearance in mesopic vision as well as photopic and scotopic vision. It is based on a two-stage model which consists of the cone and opponent stages and it assumes rod intrusion at the opponent stage. The model has the following features to describe the color appearance in mesopic vision. First, it includes a gradual and nonline...
