1. A processor comprising:
processing circuitry to clamp a distance estimate between two objects and generated using artificial intelligence to a minimum distance based at least in part on an estimated distance being less than the minimum distance, wherein the minimum distance is determined based at least in part on a first intersection point of a ray with a curve, the ray being cast from a camera through a point corresponding to a bounding shape.
