Two functions for working with the Feret diameter of labelized particles in images.
The function imFeretDiameter computes the Feret diameter for each one of the specified directions. The maximal diameter can be obtained by computing the max of the result.

The function imOrientedBox computes Feret diameter for several directions, and keep the direction that produces the minimal-area enclosing rectangle. The function drawOrientedBox can be used for visualising result.

Both functions could easily be adapted to a set of points.

Works as desired! Good documentation too.
