Fundamentals of Pattern Recognition

The Chair for Pattern Recognition and Image Processing offers yearly in the fall term a foundation course in pattern recognition.

To ensure that you get all up to date information, please also refer to the German page.

Description

The course deals with basic methods used in pattern recognition. First of all, its relation with the more general estimation theory and the most important applications are discussed. Then, the basics of pattern recognition are introduced, including the concept of equivalence classes, position invariant feature extraction and the characteristics of completeness and separability in invariance theory. In the following chapter, fast non-linear algorithms for translation invariant classification for grayscale images are dealt with. Later, similarity and affine invariant features for contour images are derived, and the mapping properties and computational complexity of these so-called Fourier descriptors are discussed. The later part of the course deals with classifier design. First of all, optimal classifiers in the stochastic sense are introduced. In a later part, the solution for the basis of non-linear regression as well as learning theory is thoroughly dealt with. This includes the optimum polynomial classifier as well as the learning theory with neural networks operating with the help of backpropagation. In the end the so-called support vector machines are introduced, which is a new statistical learning approach which learns from the given training samples and has achieved excellent results in different applications.

Admission requirements to take part in the exam

If you achieve 60% of the maximum number of points that can be gained by handing in exercices and present one exercice in front of your exercice group, you get the so called Übungsschein which states that you have taken part at the exercices. This Übungsschein is a prerequisite to be allowed to take part in the exam!
