Paper Abstract

Radon transform can transform orthogonal coordinate space to Radon space with simple rotation and shift coordinate transform relationship. Radon transform followed by MeIlin transform, i.e., Radon-Mellin transform, is shown to provide scale, rotation and shift invariant correlation in Joint transform correlator by a series of one-dimensional (1-D) MeBin transformed projection correlations to utilize many excellent devices for 1-D signal processing with the advantage of change of reference pattern in real-time and without utilizing complicated synthesized filters.
