Nusrat Sharmin presented a poster entitled "Alignment of Tractograms as Linear Assignment Problem" at CDMRI 15 - workshop on computational diffusion MRI during MICCAI 2015.
MICCAI 2015 (18th International Conference on Medical Image Computing and Computer Assisted Interventions) was held in Munich, Germany from October 5th to October 9th.

The authors propose to improve registration-based alignment of dMRI by mapping and frame the mapping problem as a rectangular linear assignment problem (RLAP). They adopt a variant of the famous Hungarian method to get the optimal solution of the RLAP. The proposed method gets validated with a tract alignment application, where the authors register two tractograms and, given one anatomical tract, segment the corresponding one in the other tractogram. On dMRI data from the Human Connectome Project, they provide experimental evidence that mapping, implemented as a RLAP, can vastly improve both the true positive rate and false discovery rate of registration-based alignment.
