Operation: measure mean diameter
The operation takes a mask and a skeleton and estimates the mean
diameter of the structure in the mask image. Areas around branching
points are not taken into account.
Options

max joint radius: The radius of the circle that will be deleted around each branching point.
Parameter
inputImage (ImagePlus): The mask of the structure to me measured.
skeleton (ImagePlus): A skeleton of the input mask.
Results
result (ImagePlus): An image that indicates the parts of the mask that have been taken into account for the calculation.
meanThickness (ResultsTable): A results table containing the estimated mean thickness of the structure in the mask image.
