template<class ArrayT>

std::vector<ArrayT*> Impala::Core::Array::InvHsiDer ( std::vector< ArrayT * > src ) [inline]

input: R, Rx, Ry, G, Gx, Gy, B, Bx, and By.

output: H_x, H_y, S_x, S_y, I_x, I_y as used by Joost van de Weijer ported from matlab code at http://lear.inrialpes.fr/people/vandeweijer/research1

Note:: :only tested for ArrayT = Array2dScalarReal64
