Design of a Framework for HDR Sequence Rendering Evaluation
  DOI :  10.2352/CIC.2005.13.1.art00003  Published OnlineJanuary 2005

A framework for evaluation of HDR video sequence rendering is proposed. We present the signal processing flow of an experimental configuration in which we placed a calibrated CRT monitor next to the HDR display to allow side-by-side evaluations. The HDR display was built using off-shelf components: a LCD panel and a DLP (Digital Light Projector). HDR images consisting of XYZ tristimulus images are converted to six channel images using HDR display characterization. The same HDR images in XYZ format can be tone mapped and rendered to the CRT display. Colorimetric measurement of random verification targets was taken from both calibrated displays and standard images were visually examined as well. Furthermore, we also evaluated how colorimetrically accurate is the image reproduction on HDR display compared to an original HDR scene. Based on the accuracy of the measurements and the visual match for the images we can conclude that we have a reasonably colorimetric accurate system to evaluate tone mapping algorithms. The specification of a computer system with processing and displaying capability for HDR video sequences is also presented showing specifications of what is required to perform this evaluation. We expect this framework to be useful as a reference to everyone trying to evaluate the accuracy of tone mapping for both HDR still image and image sequences.
