C++ code for finding camera response functions(CTFs) and creating HDR images.  Implements the 1997 paper "Recovering High Dynamic Range Radiance Maps from Photographs".


Uses the [Eigen](http://eigen.tuxfamily.org/index.php?title=Main_Page) library for linear algebra.


Current TODO list:
* Make code fail gracefully when run with images that don't exist.
* Include second executable for creating HDR images(this code here just creates the response curve)
* Include a few example images w/ response curves and info on how to use this
* Stratified sampling of the image; not pure random
* Account for pixel bloom
* Make sure code does not crash if system is under-determined.  Print warning to use to raise num_samples if system is under-determined.  Also, warn if regularization term will dominate fitting term.
