Visualizing and Communicating Errors in Rendered Images

Research output: Chapter in Book/Report/Conference proceedingBook chapterpeer-review

Abstract

In rendering research and development, it is important to have a formalized
way of visualizing and communicating how and where errors occur when
rendering with a given algorithm. Such evaluation is often done by comparing
the test image to a ground-truth reference image. We present a tool for doing
this for both low and high dynamic range images. Our tool is based on a
perception-motivated error metric, which computes an error map image. For
high dynamic range images, it also computes a visualization of the exposures
that may generate large errors.
