Multiple Hidden Markov Model for Pathological Vessel Segmentation

Figure 1

Collecting training samples and testing samples. (a) Vessel cross-section plane orthogonal to the extracted vessel axis. (b) Collecting voxel series along the rays as training samples and testing samples. The black points indicate the voxels on the ray. The rays space every 5° from the axis point. (c) One voxel series along the ray. Along each ray, we collect 18 voxels.
