Today I want to finish up my long-running discussion of Feret diameters. (Previous posts: 29-Sep-2017, 24-Oct-2017, 20-Feb-2018, and 16-Mar-2018.) Recall that the Feret diameter measures the... read more >>

Last time (if you can remember that long ago), I talked about how to find the maximum Feret diameter of a shape. The Feret diameter, sometimes called the caliper diameter, is illustrated by the diagram below. In a virtual sense, place the object to be measured inside the jaws of a caliper, with the caliper oriented at a specified angle. Close the jaws tightly on the object while maintaining that angle. The distance between the jaws is the Feret diameter at that angle.... read more >>
