Abstract

Radiometric compensation can be accomplished on nonlinear
projector-camera systems through the use of pixelwise lookup ta-
bles. Existing methods are both computationally and memory inten-
sive. Such methods are impractical to be implemented for current
high-end projector technology. In this paper, a novel computation-
ally efficient method for nonlinear radiometric compensation of pro-
jectors is proposed. The compensation accuracy of the proposed
method is assessed with the use of a spectroradiometer. Experi-
mental results show both the effectiveness of the method and the
reduction in compensation time compared to a recent state-of-the-
art method.
