- Place: Room 1022
- Abstract: 3 Sample-automated segmentationof the optic radiation on an axialbrain slice. The left side shows theegmented optic radiation on a non-diffusion-weighted image (b = 0).The corresponding diffusion [more...]
- Topic: hidden Markov random field model and the expectation-maximization algorithm

- Date: 2:00 P.M., Friday, Jan 25, 2013
- Place: Room 924
- Abstract: By incorporating both the HMRF
model and the EM algorithm into a HMRF-EM framework, an
accurate and robust segmentation can be achieved.
