Pattern recognition and location based on the Gauss-Laguerre transform
Marco Carli, Giovanni Jacovitti, Alessandro Neri · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
Recognition of patterns irrespective of their actual orientation is approached in a context of estimation theory. In particular, it is shown how using Circular Harmonic Filter banks the problem drastically simplifies from a computational viewpoint. A general purpose pattern detection/estimation scheme is finally illustrated by decomposing the images on an orthogonal basis formed by Laguerre-Gauss Harmonic Functions, and an application example is provided.
