Figure 4.
The ratio of detected voxels to all brain voxels shown as a function of v for the synthetic data using OCSVM (dot blue line), and the proposed method (solid red line). The latter is much closer to the true ratio (dash dark line) with negligible dependence on v over this range, as compared to OCSVM. (a) Network A with a true ratio of 2.64%; (b) Network B with a true ratio of 3.84%.
