Module: Multi-Scale Cylinder Correlation ()

Description:

This is an experimental module from the Xtra Library: https://xtras.amira-avizo.com.

This module combines the results of mutliple runs of the Cylinder Correlation module.

You can specify the parameters of the cylinder template for each run separately. The results will be a correlation map and an orientation field, which you can use as input for the Trace Correlation Lines module.

As a third result, a dataset is created which stores the information in which of all the separate runs the maximum value occurred, this is the maximum index map.

The combination of all the partial results is done as follows: At each voxel position, the maximum of all the intermediate correlation map values is written to the resulting correlation map.

Likewise all the voxel values of the resulting orientation map are respectively taken from the intermediate orientation map corresponding to the correlation value picked for each voxel.

Ports:

Console

Opens the Python Script Object console of the module as the active console window.

Number of Cylinder Templates

Number of different cylinder templates that can be matched with.

Length

Lengths of the respective cylinder templates to be matched with.

Angular Sampling

Angular frequencies by which the half sphere of search for the respective cylinder templates orientation is sampled.

Mask Radius

Masks radii surrounding the respective cylinder templates. These values must be larger than the corresponding values of the Outer Radius.

Outer Radius

The values of this port specify the outer radii in the case of hollow cylinder, or the cylinder radii in the case of solid cylinder, for the respective cylinder templates.

Inner Radius

The values of this port specify the inner radii in the case of hollow cylinder for the respective cylinder templates. The thickness of a cylinder wall is then computed as Outer Radius - Inner Radius. Use 0 to specify a solid cylinder.

Contrast

Contrast of the signal to be detected. Choose Bright on dark if the structures are bright on a dark background (default). Choose Dark on bright if the structures are dark on a bright background.
