Motivation
Here are some applications for the recovery of camera response curves and the creation of high dynamic range radiance maps from them.
Image Processing
Image processing techniques can be more accurate and believable when done on the irradiance map. When applied to the irradiance map, blurring is more realistic, edge detection can be more accurate, color correction is more believable, and pixel correspondence is more robust to different exposures and media. These and other applications can benefit from access to the irradiance map.
Image-Based Modeling
Scanned images are frequently used as texture maps for geometric models. Most methods assume single exposure setting, but in most cases this assumption is unrealistic. Often multiple exposures are required.
​
With this process, one can correctly fuse data from different exposure settings, and even from from different devices altogether.
BRDF Recovery
This method can assist in the creation of advanced reflection models (BRDF). Methods of BRDF recovery, which involve observing surface radiance in various directions under various lighting conditions, are more accurate when created from absolute radiance values rather than from nonlinearly mapped pixel values found in conventional images.
