// C++: class RetinaFastToneMapping
/**
* a wrapper class which allows the tone mapping algorithm of Meylan&al(2007) to be used with OpenCV.
*
* This algorithm is already implemented in thre Retina class (retina::applyFastToneMapping) but used it does not require all the retina model to be allocated. This allows a light memory use for low memory devices (smartphones, etc.
* As a summary, these are the model properties:
*
* -
* 2 stages of local luminance adaptation with a different local neighborhood for each.
*
* -
* first stage models the retina photorecetors local luminance adaptation
*
* -
* second stage models th ganglion cells local information adaptation
*
* -
* compared to the initial publication, this class uses spatio-temporal low pass filters instead of spatial only filters.
* this can help noise robustness and temporal stability for video sequence use cases.
*
*
*

/**
* applies a luminance correction (initially High Dynamic Range (HDR) tone mapping)
*
* using only the 2 local adaptation stages of the retina parvocellular channel : photoreceptors
* level and ganlion cells level. Spatio temporal filtering is applied but limited to temporal
* smoothing and eventually high frequencies attenuation. This is a lighter method than the one
* available using the regular retina::run method. It is then faster but it does not include
* complete temporal filtering nor retina spectral whitening. Then, it can have a more limited
* effect on images with a very high dynamic range. This is an adptation of the original still
* image HDR tone mapping algorithm of David Alleyson, Sabine Susstruck and Laurence Meylan's
* work, please cite: -> Meylan L., Alleysson D., and Susstrunk S., A Model of Retinal Local
