Visualizing High Dynamic Range Images in a Web Browser

Conference logo

A method for displaying HDR images with exposure control in a web browser. The project page includes a toolkit for generating web pages with HDR images.


Project image

Color correction in tone mapping

Conference logo

Color distortions due to tone-mapping are corrected by adjusting image color saturation. A model of color adjustment is built based on the data from an appearance-matching experiment.


Project image

Display adaptive tone-mapping

Conference logo

A tone-mapping algorithm that is controlled by a super-threshold visual metric. The solution takes into account display limitations, such as brightness, black level, and reflected ambient light.


Project image

Dynamic Range Independent Image Quality Assessment

Conference logo

A visual metric that is mostly invariant to contrast and tone-scale manipulations. It can detect loss of visible contrast, amplification of invisible contrast and contrast reversal.


Project image

Enhancement of Bright Video Features for High Dynamic Range Display

Conference logo

A semi-automatic method for classification of reflective and emissive objects in video, followed by brightness enhancement for display on high dynamic range displays.


Project image

Modeling a Generic Tone-Mapping Operator

Conference logo

A generic model of a local tone-mapping operator is fit to a pair of LDR and HDR images. The model is applied for backward compatible HDR image compression, analysis of tone-mapping operators and synthesis of new operators from existing ones.


Project image

Brightness of Glare Illusion

Conference logo

The perceived brightness of the glare illusion is measured in a brightness matching experiment. A simple Gaussian convolution is shown to produce similar brightness boost as a physically correct PSF model of the eye optics.
