Multiple Sclerosis Lesion Detection Using Constrained GMM and Curve Evolution

Figure 2

Illustration of the influence of the EM iterations. As the parameter estimation improves with the iterations, the segmentation induced from the model becomes more and more robust to noise. Blue-CSF; Green-GM; Yellow-WM. (a) Initial segmentation. (b) Segmentation after convergence (five EM iterations).
