Calculates
using Hough transforms
the numbers of circles in an image with radii in
a specified range. The threshold value used when counting 'particles'
in the Hough transform
window can be set so as to include incomplete
circles (low threshold) or discriminate against artefacts (high
threshold). Press the option key to bypass the dialog box. If the
current window displays a Hough
transform then this menu item changes
to 'ReCalc Size Dist...' which allows the distribution to be
recalculated for a new threshold value, entered manually or taken from
the current threshold setting.
