A Phase Locking Theory for Matching Common Parts of Two Images by Dynamic Link Architecture

Pattern recognition invariant against deformation or translation can be performed with dynamic link architecture, which has been proposed by von der Malsburg. Dynamic link is applied to many engineering examples efficiently, but has not been analyzed mathematically. We propose a mathematically tractable model of dynamic link architecture. Our model matches common parts between a template image and a data image. To analyze model mathematically, we derive the phase dynamics from the model equation. We also carry out a computer simulation to verify the mathematical theory.
