Operating volume - user specified increase in the resolution of the resulting "Ridges". It is practical experience that skeletons might benefit from the increase in resolution since their width of 1 voxels is used to simulate the objects of 0-thickness. "Increase resolution coefficient" in practice range from 1 to 3.
Interpolation - specifies the algorithm used in image upscaling.
Background detection is a part of the algorithm. Background is detected by overall smoothing of the volume. User has to specify "Radius (vox)" and the type of the smoothing Kernel.
Output parameter - specifies the result of the processing.
Elevation Map - Signal intensity volume specifying the likelihood that corresponding voxel is a ridge.
Ridge Mask: Binary ROI representing wide ridges.
Skeleton Mask: Centerlines of the Ridges represented as binary volumes.
