/**
* \class ImageSimulationMethod
* \brief Image simulation method
*
* ImageSimulationMethod converts a vectorData describing spatial distribution of materials into an image of reflectance.
* Reflectance image is computed by applying the RSR (relatives spectral response) of the satellite to the spectra obtained
* by the spectrum simulator. Then the satellite FTM is applied to compute spatial distribution of spectra.
* FTM is computed using otbResampleImageFilter and a ProlateInterpolateImageFunction.
* This method is not a true composite filter and the method UpdateData() must be called in a main program using this class.
*
*In order to avoid homogenous regions of a material, for each pixel in the region a noise is added to the reference sprectrum obtained from the spectrum
*simulator (see LabelMapToSimulatedImageFilter).
