/** @brief This algorithm decomposes image into two layers: base layer and detail layer using bilateral filter
|

|
|
and compresses contrast of the base layer thus preserving all the details.
|

|
|
|

|
|
This implementation uses regular bilateral filter from OpenCV.
|
||
|
|
|

Saturation enhancement is possible as in cv::TonemapDrago.
