the class FactoryPyramid method discreteGaussian.

/**
 * Creates an updater for discrete pyramids where a Gaussian is convolved across the input
 * prior to sub-sampling.
 *
 * @param imageType Type of input image.
 * @param sigma Gaussian sigma.  If < 0 then a sigma is selected using the radius.  Try -1.
 * @param radius Radius of the Gaussian kernel.  If < 0 then the radius is selected using sigma. Try 2.
 * @return PyramidDiscrete
