Seyed Mostafa Kia and Bao Thien Nguyen: Poster presentations at CIMeC Doctoral School Day
Doctoral School Day is a yearly event organized by CIMEC UNITN. It provides a platform for the doctoral students to share their research. At the poster session, Mostafa Seyed Kia presented a poster entitled "Reading Your Thoughts: Science or Science Fiction?" The poster presented by Bao Thien Nguyen had the title "Tractography Mapping".
In his presentation, Seyed Mostafa Kia described his work on reconstruction of visual stimuli (movie clips) based on magnetoencephalographic (MEG) brain recordings. The authors used the Discrete Cosine Transform (DCT) to extract reconstructable spatio-temporal features from both movie clips and MEG signals and claim that DCT is an effective feature extraction method to represent the spatio-temporal dynamic of brain activity as well as video features that makes the reconstruction process more feasible. However, conclude the authors, mind-reading is still on the border of science and science fiction.
Bao Thien Nguyen presented his contribution to the field of Brain Tractography Mapping. Registration of tractography is often performed by applying the transformation resulting from other images (T1, FA, DTI) to tractography data. The authors suggest another method that does not involve transformations: they try to directly map the source tractography to the target tractography by making use of a graph-based solution for tractography mapping problem. Experiments using real dMRI data demonstrate the potential of the proposed method.
