Vocabulary

Label

Label is a type of an annotated object (e.g. person, car, vehicle, etc.)

---

Attribute

Attribute is a property of an annotated object (e.g. color, model, quality, etc.). There are two types of attributes:

Unique

Unique immutable and can't be changed from frame to frame (e.g. age, gender, color, etc.)

Temporary

Temporary mutable and can be changed on any frame (e.g. quality, pose, truncated, etc.)

---

Track

Track is a set of shapes on different frames which corresponds to one object. Tracks are created in Track mode

---

Annotation

Annotation is a set of shapes and tracks. There are several types of annotations:

• Manual which is created by a person
• Semi-automatic which is created mainly automatically, but the user provides some data (e.g. interpolation)
• Automatic which is created automatically without a person in the loop

---

Approximation

Approximation allows you to reduce the number of points in the polygon. Can be used to reduce the annotation file and to facilitate editing polygons.

---

Trackable

Trackable object will be tracked automatically if the previous frame was a latest keyframe for the object. More details in the section {{< ilink "/docs/annotation/auto-annotation/ai-tools#trackers" "trackers" >}}.

---

Mode

Interpolation

Mode for video annotation, which uses track objects. Only objects on keyframes are manually annotation, and intermediate frames are linearly interpolated.

Annotation

Mode for images annotation, which uses shape objects.

---

Dimension

Depends on the task data type that is defined when the {{< ilink "/docs/workspace/tasks-page#create-annotation-task" "task is created" >}}.

2D

The data format of 2d tasks are images and videos. Related sections:

• {{< ilink "/docs/workspace/tasks-page#create-annotation-task" "Creating an annotation task" >}}

3D

The data format of 3d tasks is a cloud of points. {{< ilink "/docs/workspace/tasks-page#data-formats-for-a-3d-task" "Data formats for a 3D task" >}}

---

State

State of the job. The state can be changed by an assigned user in {{< ilink "/docs/annotation/annotation-editor/navbar.md#top-panel" "the menu inside the job" >}}. There are several possible states: new, in progress, rejected, completed.

---

Stage

Stage of the job. The stage is specified with the drop-down list on the {{< ilink "/docs/workspace/tasks-page" "task page" >}}. There are three stages: annotation, validation or acceptance. This value affects the task progress bar.

---

Subset

A project can have subsets. Subsets are groups for tasks that make it easier to work with the dataset. It could be test, train, validation or custom subset.

---

Credentials

Under credentials is understood Key & secret key, Account name and token, Anonymous access, Key file. Used to {{< ilink "/docs/workspace/attach-cloud-storage#attach-new-cloud-storage" "attach cloud storage" >}}.

---

Resource

Under resource is understood bucket name or container name. Used to {{< ilink "/docs/workspace/attach-cloud-storage#attach-new-cloud-storage" "attach cloud storage" >}}.
