Annotating using bounding boxes, keypoints, polygons, and lines.

The bounding box tool and keypoint tool on the left side of the video viewer panel. Once you select the tool type you will then select the type of entity that you want to create. The selections you will have available will depend on the configuration of your labeling ontology.

	Bounding Box
	Polygon
	Polyline

How to use the bounding box tool

1) How to draw a bounding box

Select: Create New Annotation

You can start creating a new annotation by clicking the bounding box tool. 

Select: Annotation Types

You will be given options after you click on the tool. These options vary depending on how you have configured the task ontology. Here is what it looks like: 

Drawing a bounding box

Select: Classifications/Relationships

• The annotations labels will appear in the grey area below. 
• You are required to select classifications and/or relationships of the annotations depending on how you have configured the task ontology.

Selecting classifications/relationships

Repeat the steps above to add more annotations.

2) How to adjust the size of the bounding box

• The size of the bounding box can be adjusted according to the object in the video. 
• You may click at one of the four edges of the bounding box to adjust its size while maintaining its shape.

3) How to adjust shape of the bounding box

• The shape of the bounding box can be adjusted according to the object in the video. 
• You may drag the lines of the bounding boxes to adjust its shape.

4) How to adjust the position of the bounding box

• You can adjust the position of the bounding box.
• You may click in the middle of the box and drag to adjust the position while maintaining the shape.

Repeat the steps above if you would like to add more annotations.

2) How to adjust the position of the keypoint

• You can adjust the position of the keypoint.
• You may click in the middle of the keypoint and drag to adjust the position while maintaining the shape.

How to annotate using polygons and polylines

1. Draw a polygon or polyline.

• Click the polygon or polyline icons in the toolbar.
• Click to add vertices to define the shape.
• Click Enter, Close Shape in the Options panel, or click the first vertex to close a polygon.
• Click Enter or End Line in the Options panel to end the line. 
• Select and drag vertices to to edit the shapes.
• Select the Add or Delete radio buttons to switch between modes to add or delete points from a shape.
• Click an existing vertex to delete it in delete mode.
• Hover over the midpoint of a segment and click the mid-point vertex to add it as a new vertex.

2. Set classifications and relationships

Depending on the ontology set by your administrator, you may have classifications or relationships to set on specific frame of the video. Please consult your annotation guidelines.
