Module: Fiber Shape Statistics ()

Description:

Fiber Shape Statistics internally reconstructs a labeled fiber data from a grayscale and a mask by converting the input spatial graph to a binarized representation (using Convert Geometry To Label) and growing it within the mask using watersheding (using Marker Based Watershed Inside Mask). This representation is then used to calculate the volume fraction of each fiber and deduce various statistics including:

• Fiber ID: The ID of the studied fiber.
• Curved length: The length of the studied fiber.
• Volume: The volume of the studied fiber.
• Area: The area of the studied fiber.
• Diameter: The average diameter of the studied fiber. (diameter=2*sqrt(volume3d/(PI*length))
• Cross section area: This value is equal to fiber volume divided by fiber length.
• Cross section perimeter: This value is equal to fiber area divided by fiber length .

Connections:

Data [required]
This port is used to select the input spatial graph.

Mask [required]
This port is used to select the input mask data. Voxel value is 1 when it is a fiber, 0 otherwise.

Grayscale [required]
This port is used to select the grayscale image associated with the input spatial graph.

Ports:

Output

This port is used to select outputs. There are two choices:
Spreadsheet: creates a tabbed spreadsheet.
Spatial Graph: creates a spatial graph with statistics stored as attributes.
