// This example illustrates the use of the binary threshold image filter.
// This filter is used to transform an image into a binary image by changing
// the pixel values according to the rule illustrated in
// Figure~\ref{fig:BinaryThresholdTransferFunction}. The user defines two
// thresholds---Upper and Lower---and two intensity values---Inside and
// Outside. For each pixel in the input image, the value of the pixel is
// compared with the lower and upper thresholds. If the pixel value is inside
// the range defined by $[Lower,Upper]$ the output pixel is assigned the
// InsideValue. Otherwise the output pixels are assigned to the OutsideValue.
// Thresholding is commonly applied as the last operation of a segmentation
// pipeline.
