AlignExposures 
The base class for algorithms that align images of the same scene with different exposures

AlignMTB 
This algorithm converts images to median threshold bitmaps (1 for pixels brighter than median
luminance and 0 otherwise) and than aligns the resulting bitmaps using bit operations.

CalibrateCRF 
The base class for camera response calibration algorithms.

CalibrateDebevec 
Inverse camera response function is extracted for each brightness value by minimizing an objective
function as linear system.

CalibrateRobertson 
Inverse camera response function is extracted for each brightness value by minimizing an objective
function as linear system.

MergeDebevec 
The resulting HDR image is calculated as weighted average of the exposures considering exposure
values and camera response.

MergeExposures 
The base class algorithms that can merge exposure sequence to a single image.

MergeMertens 
Pixels are weighted using contrast, saturation and wellexposedness measures, than images are
combined using laplacian pyramids.

MergeRobertson 
The resulting HDR image is calculated as weighted average of the exposures considering exposure
values and camera response.

Tonemap 
Base class for tonemapping algorithms  tools that are used to map HDR image to 8bit range.

TonemapDrago 
Adaptive logarithmic mapping is a fast global tonemapping algorithm that scales the image in
logarithmic domain.

TonemapMantiuk 
This algorithm transforms image to contrast using gradients on all levels of gaussian pyramid,
transforms contrast values to HVS response and scales the response.

TonemapReinhard 
This is a global tonemapping operator that models human visual system.
