1 July 1992 Hierarchical filter sets for distortion-invariant OPR
Author Affiliations +
Our research group at Carnegie Mellon University has devised a large number of new distortion-invariant optical correlation filters. We briefly review our hierarchical inference approach to scene analysis, our minimum noise and correlation energy (MINACE) filters, the use of morphological hit-miss (rank-order) and MINACE filters for detection, and the use of MINACE filters with different control parameters c for all three levels of scene analysis (detection, recognition, identification). We then detail new generalized rotation-invariant filters with initial test results.
