Abstract: An imaging system and method with an arrangement for sensing the performance of an optical system and providing data in response thereto and electronically correcting nonuniformity in the performance of the optical system in response thereto. In the illustrative application, the nonuniformity is a porthole effect. In the preferred embodiment, the arrangement for correcting includes an arrangement for providing an inverse distortion to an output of the system electronically. The inverse distortion is applied by generating a plurality of spatial correction coefficients from the performance data, storing the coefficients and applying the coefficients to current data from the optical system. The spatial correction coefficients are statistically generated gain and level correction defect maps. The present teachings should enable a correction of optical distortion in nonideal electro-optical systems without requiring additional optics.

Abstract: A computer model of a physical structure (or object) can be generated using context-based hypothesis testing. For a set of point data, a user selects a context specifying a geometric category corresponding to the structure shape. The user specifies at least one seed point from the set that lies on a surface of the structure of interest. Using the context and point data, the system loads points in a region near the seed point(s), and determines the dimensions and orientation of an initial surface component in the context that corresponds to those points. If the selected component is supported by the points, that component can be added to a computer model of the surface. The system can repeatedly find points near a possible extension of the surface model, using the context and current surface component(s) to generate hypotheses for extending the surface model to these points.
