Generates a HDRI / radiance image from given image stack.
Parameters: |
- image_stack (ImageStack) – Stack of single channel or multi-channel floating point images. The
stack is assumed to be representing linear values except if
camera_response_functions argument is provided.
- weighting_function (callable, optional) – Weighting function \(w\).
- weighting_average (bool, optional) – Enables weighting function \(w\) computation on channels average
instead of on a per channel basis.
- camera_response_functions (array_like, optional) – Camera response functions \(g(z)\) of the imaging system / camera
if the stack is representing non linear values.
