The title of this EU BIOMED 2 project is Visual Object Recognition: Cognitive neuropsychological, psychopharmacological, and neuroimaging (PET and fMRI) studies. The aim of the project is to combine the research skills, interest and resources of research groups in cognitive and clinical neuropsychology with those of research groups in psychofarmacology and neuroimaging for a concerted effort at illuminating basic problems in visual object recognition. The participating institutions are:
  • Psychological Laboratory, University of Copenhagen (Denmark).
  • Cognitive Science Research Center, University of Birmingham (UK).
  • Dept. de Psychiatrie, Hospitaux Universitaires de Strasbourg (France).
  • Dept. Neurology, Rigshospitalet (Denmark).
  • Dept. Mathematical Modelling, Technical University of Denmark.
The proposed studies are based on a cognitive model of visual object recognition, and deigned to provide answers to poen issues particularly relating to the so-called intermediate stages of visual perception. We will also use the cognitive data in further developments of imaging data analyses with the specific goals of increasing spatial resolution and modeling non-linear relationships. The role of the DTU group is to develop and benchmark a MATLAB toolbox for analysis of PET and MRI scan comprising: 1) Inhomogeneous Markov field filtering of functional scans using anatomical information based on structural MRI scans. 2) Neural net modeling with adaptive architectures (network pruning) and test for statistical significance of the non-linearity. 3) Visualisation of the non-linear model using the saliency map.
