Image analysis and probabilistic robotics 
In image analysis, we are often dealing with a large amount of uncertainty. One way to handle 
uncertainty is to take care that images are recorded in a standard way with good contrast between 
object and background. However, in many applications we want to handle complex images with high 
uncertainty.  
In robotics for example, decisions often have to be taken by a robot based on information extracted 
from complex scenes and a probabilistic framework is then needed to handle these uncertainties. This 
is often referred to as ‘probabilistic robotics’ and includes approaches like particle filters and (partially 
observable) Markov decision processes. 
In this talk, I want to show two vision-based robot applications, one for autonomous navigation and 
one for weed detection. In the first application a robot has to navigate autonomously in a field of maize 
between rows of plants. In the second application we will try to detect weed plants in grassland, using 
Fourier methods in a particle filter context.

Dr van der Heijden is a senior scientist at Biometris, the group of mathematicians and statisticians 
of Wageningen UR in the Netherlands. His research is focused on the application of image analysis in 
life sciences. He has been studying digital shape analysis and spectroscopic imaging for different 
applications, including plant variety testing, plant sorting and microscopy research. Current research 
interests include probabilistic robotics and feature extraction in complex environments for applications 
as large scale phenotyping of plants, virus detection in tulips and autonomous field robots.
