== Shape Features ==
* '''Min. Feret Diameter''': the minimum distance between the two parallel tangents touching the particle outline in all directions.
* '''Max. Inscr. Circle Diameter''': The diameter of the maximum inscribed circle.
* '''Area eq. circle diameter''': Equivalent circle diameter <math>2\sqrt{\frac{A}{\pi}}</math>* '''Long Side Minimum Bounding Rectangle'''(<math>L</math>): The larger side of the minimum bounding rectangle.* '''Short Side Minimum Bounding Rectangle'''(<math>S</math>): The smaller side of the minimum bounding rectangle.
* '''Aspect Ratio''': Defined as <math>L/S</math>
