AngScale 
Find an appropriate delta to use for getting grid intervals.

BoxSmoother 
Do a box car smoothing of an image

Contourer 
Find contours of an image.

CoordinateFormatter 
This class provides methods to encode coordinates
to a variety of precisions in both sexagesimal and decimal representations.

GaussSmoother 

Gridder 
This class is used to find the lines and text to draw coordinate grid overlays.

NormedGaussSmoother 

PolarData 
Compute compound polarization parameters from the basic I,Q,U.

ThresholdMedianSmoother 
Do a median smoothing for all pixels that differ from the median by
more then the threshold
Settings used:
MedianSmoother=size[,threshold]
Size gives the size of the box in which the median is computed
This must be an odd integer >= 3
Threshold is the change beyond which the pixel will be smoothed
Assumed to be 0 if omitted which means that all pixels are smoothed.

WeightedSmoother 
Smooth an image using a rectangular array of weights
