Oriented Bounding Box

A regular Bounding Box and an Oriented Bounding Box are configured in the same way. However, the difference lies in the fact that the Oriented Bounding Box can be rotated to match the object's location. In other words, an Oriented Bounding Box provides more flexibility when it comes to object detection.

Oriented Bounding Box setting window

Please fill in the titles (eng), (ru), and (ua) with the corresponding names in each

Only fill in Title (ru) and Title (ua) if you want to get a human readable localized class name.

To choose the color of an object, use the color palette.

Color palette

Select the item that best suits your needs in the Form Interpolation field. This value will determine whether the annotated object will move smoothly frame by frame (for example, for a video project), only on key frames, or appear exclusively on key frames.

In the ID input field, enter the title which will be used for export.

To show the ID, type, and size in the editor, tick the corresponding checkboxes in the settings.

By ticking the "export containing bounding box" you will export the coordinates of the vertices of the Bounding Box.

While checked, the "Export as polygon" describes all the shape complexity including the holes.

To export the object as a mask, select the Export to PNG option.

To export all masks to a common picture, select the Export to combined PNG option.

This function is only available for Oriented Bounding Box, Bounding Box, Polygon, and Bitmap. So all the objects with ticked checkbox in class setting will be exported in one image.

When the Round point coordinates to integers when exporting option is selected, coordinate numbers will be rounded to integers during export.

When exporting you can truncate the object to the image dimensions. By selecting this option, any part of the object that falls outside the frame boundaries will be automatically cropped, and those coordinates will not be displayed.

The other option is to trim any parts of the object that are covered by other objects. This function is used when exporting an object to the exported image.

The access modes available are:

• Edit objects: this mode allows users to create or delete the object.

• Edit attributes: this mode only allows users to edit the attributes of the polygon, but not the object itself.

• Read-only: this mode allows users to view the object, but restricts them from editing it.

Private checkbox - if you click this checkbox, the object will not be displayed in the json export.
