| Abstract: | Using a circular harmonic filter or a phase-only circular harmnnic filter for rotation-invariant discrimination between almost similar patterns, a new method for determining the circular harmonic expansion center is presented. This method may obtain better discrimination compared with the conventional method; especially, it is appropriate to phase-only circular harmonic filter. In addition, the results of the computer simulation are given. |
