Purpose

The module ClusterToMarkers generates a marker for each cluster in an ML image.

A cluster is defined as the set of voxels with the same integer value. The input image needs to be of integer type. The cluster voxels do not need to form a connected component.

Parameter Fields

Field Index

Background Value: Integer

Coordinate System Mode: Enum

Marker Mode: Enum

progress: Double

Update: Trigger

Update Mode: Enum

Visible Fields

Background Value

name: backgroundValue, type: Integer, default: 0

Sets a background value; voxels with this value are not considered to belong to any cluster and no marker is generated for voxels with this value.

Marker Mode

name: markerMode, type: Enum, default: Center

Defines the output marker mode.

The type of the marker is always set to the number of voxels in a cluster.

Values:

Title	Name	Description
​Center	​Center	​For each cluster, a marker is generated in the center of gravity of all cluster voxels.
​Bounding Box	​BoundingBox	​For each cluster, the marker’s pos is set to the min bounding box corner and the vec of the marker points to the max bounding box corner.

Coordinate System Mode

name: coordinateSystemMode, type: Enum, default: World

Defines the coordinate system mode.

Values:

Title	Name	Description
​World	​World	​All positions and vectors (for bounding boxes) are in world space of the input image.
​Voxel	​Voxel	​All positions and vectors (for bounding boxes) are in voxel space of the input image.

Update Mode

name: updateMode, type: Enum, default: Off

Defines the update mode.

Values:

Title	Name	Description
​Off	​Off	​No update on any change.
​Clear	​Clear	​The output marker list is cleared on any input/parameter change.
​Update	​Update	​The output marker list is filled anew on any input/parameter change.

Update

name: update, type: Trigger

When pressed, the output marker list is filled anew.
