text: Nonlinear spatial transforms and fuzzy pattern classification with unimodal
potential functions are already established in signal processing. They have proved
to be excellent tools in feature extraction and classification. We propose an
inspection method for pattern recognition and classification of two dimensional
translation variant security elements such as stripes, kinegrams and others, which
are widely used as applications in bank note printing. The system is based on
discrete non linear translation invariant circular transforms and fuzzy pattern
classification. Nonlinear discrete circular transforms are adaptable transforms,
which can be optimized for different application tasks, such as translation variant
object analysis and position location. They are mainly used as generators for
feature vectors. Even though, the feature vector is theoretically translation
invariant, the object movement creates a translation tolerant feature vector,
because in real systems and applications many problems can occur, such as signal
and optical distortions. Therefore, the features should be further analysed by
a fuzzy pattern classifier. Implementation of the transforms and fuzzy pattern
classifier in radix-2-structures is possible, allowing fast calculations with
a computational complexity of O(N) up to O(Nld(N)). Furthermore, the algorithms
can be implemented in one Field Programmable Gate Array (FPGA), which operates
with 40 MHz clock rate.
