Post-Process Ground Truth Object

Select, merge, and setup training data for object detectors

Select labels, change file paths to the data, and merge ground truth object. You can share ground truth objects with labeling colleagues, to continue labeling, training, such as an object detector or semantic segmentation network.

To share and review image labeling with colleagues, consider creating a project within the Image Labeling app. For more details, see Get Started with Team-Based Labeling.
