Abstract |
The purpose of this study is to evaluate the accuracy of luminance maps generated from five types of HDRI builder(High Dynamic Ranging Image builder) which include Photosphere, Bracket, Picturenaut, Luminance HDR and Photoshop. To accomplish this goal a set of experiments was conducted. In order to assess the luminance values of the HDR image from HDR image builder, the values had to be compared to the ones obtained from imaging photometer. After comparing measured luminance data using imaging photometer with those retrieved from the HDR images, Photosphere error rate estimated at 3% below. |
