Module: Distance Map For Skeleton ()

Description:

Calculates a distance map from a label image. In a distance map the value of each voxel is equal to the distance to the nearest border voxel. In the context of skeletonizing filamentous structures a distance map is needed on the one hand to guide the thinning procedure and on the other hand to provide an estimate of the thickness (radius) of a fiber. The module can be used together with Thinner to calculate the centerline of filamentous structures. Distance Map For Skeleton is also engaged internally when using the Auto Skeleton module. Press Apply to trigger computation.

Connections:

Data [required]
Label image to be processed. Can be a regular Label Field or of type Large Disk Data in which case the output is of the same type.

Ports:

Filename

This port is available only if the module is attached to a Large Disk Data object. Specify here the name of the output file.

Max Radius

The value at this port specifies the maximum radius (in voxel) an object may have for the distance transformation to be calculated correctly.

Use result

Status of this port defines if new result object should be created on each computation on existing one, connected to this module, should be used. Bu default it is selected that existing result should be reused.
