Create label definitions table from label definition creator object for multisignal workflow

Syntax

labelDefs = create(ldc)

Description

labelDefs = create(ldc) creates a label definitions table, labelDefs, from the labelDefinitionCreatorMultisignal object ldc. You can import the labelDefs table into the Ground Truth Labeler app to label ground truth data.

Examples

Create Label Definitions Table from Label Definition Creator Object for Multisignal Workflow

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 value the 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 value the 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)
