Data Mining and Multivariate Analysis
Project description
The activities in this project involved two
Diploma projects (Christina Johansson, summer/fall 1998 and Mikael
Nordström, summer/fall 1999), and 20% work by Stefan Arnborg.
The first Diploma project [1] involved assessment
of computational and statistical methods for handling image information,
and a study of the capabilities of the CBA program (developed by
Lennart Thurfjell, Uppsala) on a set of SPECT/MR images that were
obtained from other ongoing investigations.
The second Diploma project [2] involved investigating
segmentation methods by anisotropic diffusion, using the GOP method
(Context Vision, Linköping), SPM (Wellcome, London), AIR (UCLA),
and BRAINS (University of Iowa).
A practical result of the second project has been the definition
of a Workup adapted from the University of Iowa (MHRC) workup, with
the BRAINS and AIR programs [3].
This workup is described under the Brain
Morphology project. A current activity in brain imaging is development,
by doctoral student Roger Hult, Uppsala University, of improved
segmentation in the BRAINS II software and automated co-registration
of post-mortem brain slice images obtained by cryosectioning methods.
