Image Labeling

Interactive image labeling for object detection, semantic segmentation, and image classification

Use the Image Labeler app to interactively label ground truth data in a collection of images. You can label rectangular regions of interest (ROIs) for object detection, pixels for semantic segmentation, and scenes for image classification. The app also includes computer vision algorithms to automate the labeling of ground truth data for use with detection and tracking algorithms. It also provides an API and workflow that enables you to import your own algorithms to automate the labeling of ground truth data.

To get started labeling a collection of images, see Get Started with the Image Labeler.
