Purpose

The module MaskToMarkers creates a list of ml.XMarker from a mask image.

An XMarker is created for each voxel in the input image that has a gray value greater than Lower Threshold (default: 0).

Windows

Input Fields

input0

name: input0, type: Image

input1 (hidden)

name: input1, type: Image

Optional vector input image. Data must be of type vec3 or vecf3.

Output Fields

outputXMarkerList

name: outputXMarkerList, type: XMarkerList(MLBase)

For accessing this object via scripting, see the Scripting Reference: MLXMarkerListWrapper.

Parameter Fields

Field Index

Lower Threshold: Double

Marker Type: Enum

Mode: Enum

progress: Double

Type: Integer

Update: Trigger

Vector Mode: Enum

Visible Fields

Lower Threshold

name: lowerThreshold, type: Double, default: 0

Sets an input voxel value above which markers shall be generated.

Marker Type

name: setType, type: Enum, default: User, deprecated name: markerIDMode

Defines which value is set as type information to the generated markers.

Values:

Title	Name	Description
​User	​User	​The Type is set to each generated marker.
​Voxel Value	​VoxelValue	​The original voxel value is used as the type for the generated marker at that position. Floating point values are truncated to integers; see Vector Mode for a similar option that retains decimal digits.

Type

name: type, type: Integer, default: 0, deprecated name: markerID

Sets the value that is used as a type value for all markers if Marker Type is set to User.

Mode

name: updateMode, type: Enum, default: Off, deprecated name: autoCalc

Defines the update mode of the module.

Values:

Title	Name	Deprecated Name	Description
​Off	​Off	​FALSE	​The module does not react to any field change.
​Auto Update	​AutoUpdate	​TRUE	​The module computes a new marker list on any field change.
​Auto Clear	​AutoClear		​The module clear the output marker list on any field change.

Vector Mode

name: vectorMode, type: Enum, default: Zero, deprecated name: useVectorInput

Defines how the vector component of the markers shall be initialized.

Values:

Title	Name	Deprecated Name	Description
​Zero	​Zero	​FALSE	​Initialize all vector components to zeros (default).
​Voxel Value	​VoxelValue		​Write the voxel value into the z component. Similar to setting a marker’s type to the voxel value (see Marker Type above), but retains decimal digits of floating point input.
​Vector Input	​VectorInput	​TRUE	​Set a marker’s vector to corresponding vec3(f) value read from second input; the vector will be filled with zeros if no valid vector image is attached.

Update

name: update, type: Trigger, deprecated name: Calculate

When pressed, the module updates its output marker list.

Hidden Fields

progress

name: progress, type: Double, persistent: no
