Inhalt:
The goal of this lecture is to familiarize the students with the overall pipeline of a pattern recognition system. The various steps involved from data capture to pattern classification are presented. The lectures start with a short introduction, where the nomenclature is defined. Commonly used preprocessing methods are then described. A key component of pattern recognition is feature extraction. Thus, several techniques for feature computation will be presented including Walsh transform, Haar transform, linear predictive coding (LPC), wavelets, moments, principal component analysis (PCA) and linear discriminant analysis (LDA). The lectures conclude with a basic introduction to classification. The principles of statistical, distribution-free and non-parametric classification approaches will be presented. Within this context we will cover Bayesian and Gaussian classifiers, as well as artificial neural networks.
Lernziele und Kompetenzen:
The students
explain the general pipeline of a pattern recognition system

apply the principle of maximum likelihood estimation to Gaussian probability density functions
apply various low- and high-pass filters, as well as non-linear filters (homomorphic transformations, cepstrum, morphological operations, rank operations)
apply various normalization methods
understand the curse of dimensionality
explain various heuristic feature extraction methods, e.g.projection to orthogonal bases (Fourier transform, Walsh/Hadamard transform, Haar transform), Linear Predictive Coding, geometric moments, feature extraction via filtering, wavelets)
