+ *  \brief This functor is the base for all texture functors.
  *
- *  It uses a neighborhood and an offset (m_Offset)  to compute texture.
+ *  It uses a neighborhood iterator which radius is the one of the considered 
+ *  neighborhood plsu an offset (m_Offset) to compute texture.
  *  It computes the mean, standard deviation of the two areas and the joint histogram using
  *  Scott formula for the bins lengths computation.
  *  TIterInput is an iterator, TOutput is a PixelType.
