  • Artificial Neural Networks in Medicine and Biology
  • 2000
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
    • This book contains the proceedings of ANNIMAB-1, the first international conference on artificial neural networks in medicine and biology. Comprising a selection of papers from leading researchers in the field, it summarises the state-of-the-art, analyses the relationship between ANN techniques and other available methods and points to possible future biomedical and medical uses of ANNs.

  • A canonical correlation approach to exploratory data analysis in fMRI
  • 2002
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • A computationally efficient data-driven method for exploratory analysis of functional MRI data is presented. The basic idea is to reveal underlying components in the fMRI data that have maximum autocorrelation. The tool for accomplishing this task is Canonical Correlation Analysis. The proposed method is more robust and much more computationally efficient than independent component analysis, which previously has been applied in fMRI.

  • Finding Efficient Nonlinear Visual Operators using Canonical Correlation Analysis
  • 2000
  • Ingår i: Proceedings of the SSAB Symposium on Image Analysis. - Linköping : Linköpings universitet. ; , s. 13-16
  • Konferensbidrag (refereegranskat)abstract
    • This paper presents a general strategy for designing efficient visual operators. The approach is highly task oriented and what constitutes the relevant information is defined by a set of examples. The examples are pairs of images displaying a strong dependence in the chosen feature but are otherwise independent. Particularly important concepts in the work are mutual information and canonical correlation. Visual operators learned from examples are presented, e.g. local shift invariant orientation operators and image content invariant disparity operators. Interesting similarities to biological vision functions are observed.

  • FSED - feature selective edge detection
  • 2000
  • Ingår i: Proceedings of 15th International Conference on Pattern Recognition, Barcelona. - : IEEE. - 0769507506
  • Konferensbidrag (refereegranskat)abstract
    • We present a method that finds edges between certain image features, e.g. gray-levels, and disregards edges between other features. The method uses a channel representation of the features and performs normalized convolution using the channel values as certainties. This means that areas with certain features can be disregarded by the edge filter. The method provides an important tool for finding tissue specific edges in medical images, as demonstrated by an MR-image example.

  • A Correlation Framwork For Functional Mri Data Analysis.
  • 2001
  • Ingår i: Proceedings of SCIA 2001. Bergen,2001. - 8299594006 ; , s. 3-9
  • Konferensbidrag (refereegranskat)abstract
    • A correlation framework for detecting brain activity in functional MRI data is presented. In this framework, a novel method based on canonical correlation analysis follows as a natural extension of established analysis methods. The new method shows very good detection performance. This is demonstrated by localizing brain areas which control finger movements and areas which are involved in numerical mental calculation.
