Auto Polygons

The Auto polygon tool allows you to boost your labeling productivity.

You create a bounding box around the object you wish to label and an AI automatically transforms this bounding box into a precise polygon around your object.

Auto Polygon. The fastest way to create a polygon around your object.

Refinements

Move or add Auto Polygon keypoints

You can refine the automatically generated polygons by simply moving the target keypoint and/or adding inside keypoints and outside keypoints .

This is as simple as moving the target keypoint and/or doing a click inside or outside the created polygon.

  • Target keypoint. It must always be on the object you wish to label. Else move it on the object.

  • Outside keypoint. A click inside the polygon will add an outside keypoint and exclude this area from the polygon label.

  • Inside keypoint. A click outside the polygon will add an inside keypoint and include this area to the polygon label.

Always start by moving the target keypoint to another position on the object if the generated polygon is not good enough. Only after adjusting the target keypoint should you start adding inside and outside keypoints.

Easily adjust an Auto Polygon geometry by adding inside or outside keypoints

Manually adjust the polygon's geometry

  • Click on to activate the selection mode (or press v for the shortcut)

  • Click on the polygon you want to edit

  • Select the polygon edition mode (next to the class selection menu in the top left). You can press e to switch between both edition modes.

  • You can now drag any points on the contour to adjust the polygon geometry

This edition mode is also illustrated in the above video.
