**Occluded**
|
|
Occlusion is an attribute used if an object is occluded by another object or
|
|
isn't fully visible on the frame. Use `Q` shortcut to set the property
|
|
quickly.
|
|
|
|
|
|
|
|
Example: the three cars on the figure below should be labeled as **occluded**.
|
|
|
|
|
|
|
|
If a frame contains too many objects and it is difficult to annotate them
|
|
due to many shapes placed mostly in the same place, it makes sense
|
|
to lock them. Shapes for locked objects are transparent, and it is easy to
|
|
annotate new objects. Besides, you can't change previously annotated objects
|
|
by accident. Shortcut: `L`.
