FiftyOne Video Timeline: Find Gaps in Object Tracks

FiftyOne 1.22.0 introduces a read-only video timeline in Explore mode that displays each tracked object as interval bars for its contiguous labeled spans, allowing reviewers to identify annotation gaps without entering editing tools. Using the ten-clip quickstart-video dashcam dataset, the analysis found that only 2 of 195 tracked objects contained gaps, for an overall dropout rate of 0.52%, indicating generally high annotation quality. The most significant issue was a vehicle that remained visibly on screen but lacked a bounding box for 54 consecutive frames, or 1.8 seconds, before reappearing under the same track ID. The article explains that grouping frame-level detections by label and track index can detect such discontinuities in any tracked video dataset, helping quality-assurance teams identify defects that may affect applications such as autonomous driving, traffic monitoring, retail analytics, sports, security, and wildlife observation.
