Manual Labeling for Object Detection

1. Labeling AI's Labeling Tool

Use the Object Detection labeling task tool at DS2.ai for convenient manual labeling. Labeling AI supports labeling using various methods. From labeling using simple and easy-to-use bounding boxes or polygons to more advanced labeling functions such as magic tools, you can perform data labeling. Let's take a closer look at the differences between the labeling methods supported by Labeling AI and the application standards.

2. Labeling methods supported in LABELING AI

DS2.ai supports labeling of bounding boxes, polylines, polygons, and magic tools.

  • Bounding box: Recognize objects as rectangular boxes
