/** \class LeeImageFilter
* \brief Applique un filtre de dbruitage sur une image.
* \brief Anti-speckle image filter
*
* Ce filtre correspond au filtre Anti-Speckle de LEE :
* This class implements Lee's filter for despeckleing of SAR images.
*
* R = E[I] + b(I-E[I]) avec b = C²r / ( C²r + C²v )
* Cv = 1 / sqrt(L) avec L le nombre de vues
* Cr = sqrt(Var(I)) / E[I] avec Var(I) = E[I²] - E[I]²
* \f[R = E[I] + b(I-E[I]) \f] with \f[b = C^2_r / ( C^2_r + C^2_v )\f]
* C_v = frac{1}{\sqrt{L}} with
* \f[L\f] the number of looks and
* \f[C_r = \frac{sqrt{Var(I)}}{E[I]} \f] with \f[Var(I) = E[I^2] - E[I]^2\f]
