Radiometric Response Functions in OpenCV

I recently started reading up on how to construct composite high-dynamic-range (HDR) images programmatically. The reason why is because I had been thinking about why traditional cameras have dropped the ball on in-camera HDR when compared to their mobile phone brethren (that’s a thought for another day). There are a number of approaches for building HDR images in computer vision literature. While they differ in how to produce their final output, where they are alike is in their need for the radiometric response function of the imaging pipeline creating the images for the HDR algorithm.
