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
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.
