Observation Timeline: Annotations over time

Portal algorithms can follow objects through time and generating annotations for a given object. The Observation Timeline allows for viewing and editing an observation annotation track.

Video are a challenging space to annotate when it comes to accurately following a region of interest over time. For example, counts on those objects will grow proportionate to the frames in a video if a box is drawn on each frame, and in contrast important information can be lost without annotating all frames. The solution: tracks.

All videos include an Observation Timeline tab to view, and edit the localizations that make up the observation.
