Automated Sulcal Depth Measurement on Cortical Surface Reflecting Geometrical Properties of Sulci
Figure 3
An illustrative figure to show the local coordinates.
(A) Local coordinates, (B) “Accepted” nodes and their “Considered” nodes with temporary edges. Gray nodes are in the voxel space between the convex hull (blue nodes) and the cortical surface (yellow nodes). The edge cost is indicated by the length of the blue line.
