A theory for invariant object recognition in the frontoparallel plane
1Department of Electrical Engineering, University of Minnesota, Minneapolis, MN 55455.
Abstract:
We suggest a new computational theory for position, size, and orientation invariant recognition of planar gray-scale forms in frontoparallel view. The theory employs a spatial-frequency representation which approximates the complex-logarithmic conformally mapped Wigner distribution of a gray-scale image. Our discussion emphasizes the theoretical significance, method of computation, and practical utility of this powerful new representation for image pattern recognition.
