Classification: CPC G | IPC G

Claim 16:
17. A system comprising:
a memory;
a processor coupled to the memory; and
a communication interface coupled to the processor, wherein the processor is to detect one or more intersection edges by:
generation of a mesh around a point associated with a physical object, which is not a silhouette edge point, of a scan pattern grid with neighbor points forming shared edges between regions of the mesh; and
computation of a normal gradient across an individual shared edge to determine whether the point is lying on an intersection edge of a smooth surface:, and

detect one or more silhouette edges using the scan pattern grid and a point cloud data, wherein the processor is to detect of the one or more silhouette edges by:
determination of mixed pixels, between two objects, from the scan pattern grid; and
distinguishment of silhouette edge points of the two objects from the mixed pixels based on a determination of whether a point in the scan pattern grid is on one of the two objects.
