texture analysis texture segmentation texture synthesis texture models industrial applications automatic visual inspection systems

Prof. Hans Burkhardt Institute for Computer Science Albert-Ludwig-University of Freiburg burkhardt@informatik.uni-freiburg.de Germany

The research of the group "Texture Analysis" led by Prof. Dr.-Ing. H. Burkhardt (Univ. Freiburg) is focused on development of techniques for evaluation and analysis of textures. One of the foremost important goals of the work is the estimation and classification of texture characteristics, which allow evaluation of the sample surface. The methods must be applicable not only in particular cases, but also for various texture classes. The developed techniques will be tested on real applications, e.g. inspection of a floor surface, of honed cylindrical surfaces which influence the lifetime and the emission properties of a motor, or detection of defects in a piece of fabric in the process of quality control.
Development and validation of the methods for texture analysis require large databases of samples. It is often the case that there is not enough representative data to proove a technique. Therefore, one of the primal aims of this research is to establish problem specific databases. Large databases for the honed cylindrical and textile samples will be thus created. At the beginning, images of honed cylindrical surfaces evaluated visually by experts from the firm AE GOETZE will be incorporated into the database. This database has been provided by the Institut for Measurement and Control from Univ. Karlsruhe. A large database of textile samples for defect detection can be found on a 2 CD-ROM at the Chair of Pattern Recognition and Image Processing, Univ. Freiburg. Both databases should act as standard test sets and be used by outside researchers in the field of texture analysis.
Another important aim of the research in texture anaylsis is to define and establish criteria for the evaluation of the results. It is often difficult to compare objectively the efficiency of two methods since they do not use the same performance parameters. Thus, solely the evaluation by means of defect- or recognition- rate is not sufficient for a comparison. In order to create a unique evaluation basis, members of the group agreed to use uniform classifiers. Nevertheless, the characteristics of the computation, as well as of the processing resources play an important role in evaluating a technique. Moreover, the optimal selection of attributes for a quality criterion is another important task of the group. For many methods, it is difficult to choose only those attributes of highest relevance. Since the latter are dependent on the application, methods will be investigated for the selection of relevant attributes. In this way, the efficiency of the analysis technique will be improved.

Workshop Venue

---

The Workshop on Texture Analysis will be held in the University of Freiburg being within walking distance from the old town. Freiburg, located in the lovely surroundings of the Black Forest, has one of the oldest Universities in Germany founded in 1457 with an outstanding international reputation. This classical University with a long tradition has been recently enriched with the foundation of a new 15th Faculty for Applied Sciences consisting of two institutes: The Institute of Computer Science which will host the WTA'98 and the Institute of Microsystem Technology.
Particular to Freiburg is the medieval Old Quarter with its architectural treasures like the magnificent Gothic Cathedral (The Münster), colourful marketplace, intimate alleys and Bächle (little waterways running through the streets). Over 23,500 students and a rich program of festivals provide a very lively atmosphere. Being situated in the "three country corner" where Germany, France and Switzerland touch, Freiburg also offers many opportunities for interesting excursions e.g. by cable car up the mountain for spectacular views of the Rhine Valley and the Swiss Alps. All these make Freiburg one of the most attractive regions in Germany.
Freiburg may easily be reached by train (main route from Frankfurt to Basel) and via the airports Basel-Mulhouse, Frankfurt, Zürich, Strasbourg and Stuttgart.
