Examples
Modify Description of Attributes in Label Definition Creator Object
Load an existing label definitions table into the workspace.
labelDefFile = fullfile(toolboxdir('vision'), 'visiondata', 'labelDefsWithAttributes.mat'); ld = load(labelDefFile)
ld = struct with fields:
labelDefs: [4x4 table]
Create a label definition creator object from the label definitions table.
ldc = labelDefinitionCreator(ld.labelDefs)
ldc = labelDefinitionCreator contains the following labels: Vehicle with 0 sublabels and 3 attributes and belongs to None group. (info) Pedestrian with 0 sublabels and 0 attributes and belongs to None group. (info) LaneMarker with 0 sublabels and 2 attributes and belongs to None group. (info) TrafficLight with 1 sublabels and 0 attributes and belongs to None group. (info) For more details about attributes and sublabels, use the info method.
Modify the Description of Attribute Under a Label
Display information about the label "Vehicle".

Modify the Description of Attribute Under a Sublabel
Display information about the label "TrafficLight".
info(ldc,'TrafficLight')
Name: "TrafficLight" Type: Rectangle LabelColor: {''} Group: "None" Attributes: [] Sublabels: "Light" Description: 'Mark a tight bounding box around the traffic light. Use the sublabels to mark each individual light'
Display information about the sublabel "Light" under the label "TrafficLight".
info(ldc,'TrafficLight/Light')
Name: "Light" Type: Rectangle Attributes: ["Active" "Color"] Sublabels: [] Description: 'Mark a tight bounding box around each light.'
Display information about the attribute "Active" under the sublabel "TrafficLight/Light".
info(ldc,'TrafficLight/Light/Active')
Name: "Active" Type: Logical DefaultValue: 0 Description: 'Mark true if this light is active and false if not.'
Modify the description of the attribute "Active" under the sublabel "TrafficLight/Light".
editAttributeDescription(ldc,'TrafficLight/Light','Active','Is Active: true (DefaultValue: 1), false (DefaultValue: 0)')
Display information about the attribute "Active" to verify the modified attribute description.
info(ldc,'TrafficLight/Light/Active')
Name: "Active" Type: Logical DefaultValue: 0 Description: 'Is Active: true (DefaultValue: 1), false (DefaultValue: 0)'
