1. A system for identifying a discontinuity in the boundary of an object in an image, comprising: a light source that illuminates one or more objects; an imaging device that captures an image of the one or more objects; a processor in communication with the light source and the imaging device that calculates one or more skeletons of the one or more objects in the captured image, calculates one or more boundaries of the one or more objects in the captured image, extends a plurality of radial lines from a spine point of a skeleton of the one or more skeletons to the one or more boundaries, wherein each radial line of the plurality of radial lines intersects a boundary of the one or more boundaries at a radial endpoint producing a plurality of radial endpoints, calculates for each radial endpoint of the plurality of radial endpoints an expected radial endpoint based on two or more neighboring radial endpoints, and if the difference between the each radial endpoint and its expected radial endpoint exceeds a threshold, identifies a radial line including the each radial endpoint as a discontinuity in a boundary of an object of the one or more objects.
