  - Segmentation and feature extraction algorithms based on Wavelet Transform or Wavelet
    Packet Transform are established in pattern recognition. Especially in the field
    of texture analysis they are known to be practical. One difficulty of texture
    analysis was in the past the characterization of different printing processes.
    In this paper we present a new algorithmic concept to feature extraction of textures,
    printed by different printing techniques, without the necessity of a previous
    teaching phase. The typical characters of distinct printed textures are extracted
    by first order statistical moments of wavelet coefficients. The algorithm uses
    the 2D incomplete shift invariant Wavelet Packet Transform, resulting in a fast
    execution time of O(<i>N</i>log<sub>2</sub>(<i>N</i>)). Since the incomplete shift
    invariant Wavelet Packet Transform was exclusively defined for 1D-signals, it
    has been modified in this research. The application describes the detection of
    different printed security textures. @eng
