Open Live Script

Create an empty labelDefinitionCreatorMultisignal object.

ldc = labelDefinitionCreatorMultisignal;

Add a label called 'Vehicle'. Specify the label type as 'Rectangle' and add a description to the label.

addLabel(ldc,'Vehicle','Rectangle','Description','Bounding box for the vehicle. Use this label for cars and buses.')

Add an attribute 'IsCar' to the label 'Vehicle'. Specify the attribute type as 'logical' with the value true and add a description for the attribute.

addAttribute(ldc,'Vehicle','IsCar','logical',true,'Description','Type of vehicle')

Add an attribute 'IsBus' to the label 'Vehicle'. Specify the attribute type as 'logical' with the value false and add a description for the attribute.

addAttribute(ldc,'Vehicle','IsBus','logical',false,'Description','Type of vehicle')

Create a label definitions table from the definitions stored in the object.

labelDefs = create(ldc)
labelDefs = 2×7 table
    'Vehicle'    0    0    'None'    'Bounding box for the vehicle. Use this label for cars and buses.'    ''    1×1 struct
    'Vehicle'    1    5    'None'    'Bounding box for the vehicle. Use this label for cars and buses.'    ''    1×1 struct
