An Active Contour Model Based on Adaptive Threshold for Extraction of Cerebral Vascular Structures

Figure 2

The result of cerebral vascular structures segmented by three models. Each row relates to one patient: the first column represents the MIP images. The second column shows the segmentation result of HLS model; the third column shows the segmentation result of LLS model after noise voxels are eliminated with the connectivity filter; the last column shows the segmentation of NHLS model after noise voxels are eliminated with the connectivity.
