* \class FirstOrderTextureFeaturesImageFilter
* \brief Compute first order statistics in a neighborhood for each
* pixel.
*
* The output of this filter is a multi-component image where each
* pixel is:
* -# mean
* -# minimum
* -# maximum
* -# variance
* -# standard deviation (sigma)
* -# skewness
* -# kurtosis
* -# entropy.
* These first order statistics are computed based on a define
* neighborhood or kernel such as FlatStructuringElement::Box.
*
* The boundary is handle by only considering the pixel in the image,
* so that the boundary pixel have lets data to compute the
* statistics.
