DeepSea MOT

DeepSea MOT is a benchmark dataset for multi-object tracking on deep-sea video.

Dataset Description

DeepSea MOT consists of 4 video sequences (2 midwater, 2 benthic) with a total of 2,400 frames and 57,376 annotated objects comprising 188 tracks. The videos were captured by the Monterey Bay Aquarium Research Institute (MBARI) using remotely operated vehicles (ROVs) Doc Ricketts and Ventana in deep-sea environments, showcasing a variety of marine species and underwater scenes.

Each sequence directory contains:

• Source video (.mov): Original ROV footage
• Ground truth (gt.txt): MOT Challenge format annotations for tracking evaluation
• Sequence info (seqinfo.ini): Metadata file for TrackEval compatibility
• Images (images/): Individual frame extractions in JPG format
• YOLO labels (labels/): Object detection annotations in YOLO format (TXT files)
• Pascal VOC (xml/): Object detection annotations in Pascal VOC format (generated via RectLabel)
