Given a set of pixel values observed for several pixels in several images with different exposure times, this function returns the imaging system’s response function \(g\) as well as the log film irradiance values \(lE\) for the observed pixels.
Parameters: |
|
---|---|
Returns: | Camera response functions \(g(z)\) and log film irradiance values \(lE\). |
Return type: | tuple |
Returns the camera response functions for given image stack using Debevec (1997) method.
Image channels are sampled with \(s\) sampling function and the output samples are passed to g_solve().
Parameters: |
|
---|---|
Returns: | Camera response functions \(g(z)\). |
Return type: | ndarray |
