💀Annotation of Skeleton object

Object annotation involves selecting points from a list by their type and placing them at desired locations on the object. The sequence of points is connected by a line, forming a skeleton graph.

You can move a point individually or all points of the object together. In case the required point is not visible on the object, its setting can be skipped and the graph will be disconnected.

The corresponding buttons are provided to indicate the degree of overlapping of points.

Add new object

  1. Click "Add object" button or you can use one of the suggested shortcuts

  2. Click at the necessary point to start annotation.

  3. Keep clicking to add new vertexes in a row or choose vertex from the drop down menu.

  4. Ctrl+Click a vertex to remove it.

  5. Drag and drop a vertex to move it.

Select an object

  1. Draw a new mask.

Change the Stacking order

Move the object

Edit the object

  1. Ctrl+Click a vertex to remove it.

  2. Drag and drop a vertex to move it.

When correcting an existing skeleton, start with keyframes and then correct intermediate frames, adding new keyframes to adjust point movement.

It's important to set the necessary number of keyframes throughout the clip, and static objects should have fewer keyframes than moving ones.

Set occlusion

  1. Adjust occlusion level for each point.

The Interpolation function reduces the time it takes to annotate objects in video clips by working between skeleton keyframes. Changing any skeleton point creates a keyframe for the entire object, so all points must be corrected at once on the keyframe.
