The gamma factor depends of the contrast of the image. The constant depends on the brightness of the image.

Parameters
[out]IThe image on which gamma correction must be applied.
[in]p_maskBoolean that indicates which points must be taken into account (true value) or must be ignored (false value).

This method is an implementation of the article "Towards Real-time Hardware Gamma Correction for Dynamic Contrast Enhancement" by Jesse Scott, Michael Pusateri, IEEE Applied Imagery Pattern Recognition Workshop (AIPR 2009), 2009.

The gamma factor depends on the mean of the original image and its intensity range.

Parameters
[out]IThe image on which gamma correction must be applied.
[in]p_maskBoolean that indicates which points must be taken into account (true value) or must be ignored (false value).

This method is an implementation of the article "REDUCING ILLUMINATION BASED ON NONLINEAR GAMMA CORRECTION" by Yihua Shi, Jinfeng Yang, Renbiao Wu, International Conference on Image Processing · September 2007.

The gamma factor is the result of the sum of non-linear functions whose values depend on the pixel intensity.

Parameters
[out]IThe image on which gamma correction must be applied.
[in]p_maskBoolean that indicates which points must be taken into account (true value) or must be ignored (false value).

It works well on globally dark images that must be brightened, but overcompensate images that are already "bright enough".

Parameters
[out]IThe image on which gamma correction must be applied.
