Abstract: Identification of ships from camera images is performed by computing sets of reference silhouette images for respective reference ships for use to match the reference silhouette images with a camera image of an unidentified ship. A computer forms the set of the reference silhouette images for a reference ship is performed automatically by a processing system on the basis of at least one silhouette image of the respective reference ship. The computer generates a three dimensional model of the reference ship that represents distances of an outer surface of the reference ship to a plane on which the captured silhouette image has been mapped, the three dimensional model representing the distances as a function of position in said plane. A deck line of the reference ship is detected based on the camera image. The represented distances to the outer surface are set and/or adapted dependent on position in said plane relative to the detected deck line.

Abstract: A method, system, and computer program product for performing a lighting simulation are disclosed. The method includes the steps of receiving a three-dimensional (3D) model, receiving a set of probes, where each probe specifies a location within the 3D model and an orientation of the probe, and performing, via a processor, a lighting simulation based on the 3D model, the set of probes, and one or more light path expressions. The light path expressions are regular expressions that represent a series of events, each event representing an interaction of a ray at a location in the 3D model.
