and Colour Analysis for Machine Vision"
Prof. Matti Pietikäinen
Vision and Media Processing Group
Texture and colour analysis
are important generic research areas of machine vision with many potential
applications. This talk will give an overview of the recent research
on these topics at the Machine Vision and Media Processing Group of the
University of Oulu, Finland.
First, a short general introduction
to the activities of the group is given. Then, a nonparametric
approach to texture analysis
using simple spatial operators, like signed gray level differences or local
binary patterns, is presented. The method provides excellent performance
in difficult texture classification and segmentation problems. The
final part of the talk is concerned with our research on colour machine
vision. Methods for correcting colours of human faces in varying illumination
conditions are being developed.
European Vision Industry - strength in diversity?"
Vision Systems Consultancy
"Observation and analysis
of the European industrial machine vision market since 1986 shows that,
while European based manufacturers have a wealth of technology to offer
the world, exploitation outside their own national frontiers has not been
their strong point. There are, however, some encouraging signs that this
