1 NOISE_SMOOTH
        NOISE_SMOOTH

    Smoothes an  input  image   using   the   noise   cheating   enhancement
    method.   This  method  works only for strictly positive images.  Values
    for adjacent pixels are summed until a given total  is  reached.   Then,
    the  total  is  divided  by the number of pixels added and the result is
    used for the output pixel value.  This smoothing is very non linear  (in
    particular  no  smoothing  occur  on  pixels stronger than the smoothing
    threshold).  A parameter allows to  restrict  the  averaging  to  nearby
    pixels only :  in this case the output image is not necessarily strictly
    positive.
2 Y_NAME$
        TASK\FILE "Input image" Y_NAME$

    The name of the input image.
2 X_NAME$
        TASK\FILE "Smoothed output image" X_NAME$

    The name of the output smoothed image.
2 THRESHOLD$
        TASK\REAL "Noise threshold" THRESHOLD$

    This is the (maximum) integrated intensity at which smoothing stops.
2 SMOOTHING$
        TASK\INTEGER "Maximum number of pixels added to smooth" SMOOTHING$

    This is the maximum radius for the smoothing box (in pixels).
