A wrapper class which allows the Gipsa/Listic Labs model to be used.
This retina model allows spatio-temporal image processing (applied on still images, video sequences).
As a summary, these are the retina model properties:
1. It applies a spectral whithening (mid-frequency details enhancement);
2. high frequency spatio-temporal noise reduction;
3. low frequency luminance to be reduced (luminance range compression);
4. local logarithmic luminance compression allows details to be enhanced in low light conditions.
USE : this model can be used basically for spatio-temporal video effects but also for :
_using the getParvo method output matrix : texture analysiswith enhanced signal to noise ratio and enhanced details robust against input images luminance ranges
_using the getMagno method output matrix : motion analysis also with the previously cited properties

The retina filter includes the research contributions of phd/research collegues from which code has been redrawn by the author :
_take a look at the retinacolor.hpp module to discover Brice Chaix de Lavarene color mosaicing/demosaicing and the reference paper:
B. Chaix de Lavarene, D. Alleysson, B. Durette, J. Herault (2007). "Efficient demosaicing through recursive filtering", IEEE International Conference on Image Processing ICIP 2007
_take a look at imagelogpolprojection.hpp to discover retina spatial log sampling which originates from Barthelemy Durette phd with Jeanny Herault. A Retina / V1 cortex projection is also proposed and originates from Jeanny's discussions.
