Purpose

The module LabelByThresholdedVolume sets skeleton labels to values based on the image voxel value beneath the skeletons.

Default Label

name: defaultLabel, type: Integer, default: 12025

Sets a default label value.

If a skeleton is outside the image or its underlying voxel has a value greater than the highest threshold value, its label will be set to this value.

Threshold Label Pairs

name: thresholdLabelPairs, type: String, default: 2 12125, 5 12675, 10 12225

Sets the threshold/label pairs.

The threshold value defines the range of values up to which the following label is assigned to the skeletons.

Consider threshold values A and B with A < B. The label associated with A is set for all skeletons at voxels with values less than or equal to A, and the label associated with B is set for all skeletons at voxels with values greater than A and less than or equal to B. The labels of skeletons at voxels with values greater than B are set to Default Label.

The threshold values must increase. If, for example, the threshold values are A, B, and C with A < B < C, they must be specified in that order. Specifying A, C, B only considers A and B; the label associated with threshold value C is not set.

The threshold/label pairs string can contain any amount of whitespace, and the pairs may be divided by newlines. Using any non-numeric string invalidates the remainder of the string.

Set Nearest Label Recursively

name: setNearestLabelRecursively, type: Bool, default: FALSE

If checked, the nearest found label is set recursively down to the leaves.

Otherwise, only the skeletons within the threshold range are assigned the specified label value.
