Video Object Instance Dataset

The Video-Object-Instance (NTU-VOI) dataset from NTU’s ROSE Lab is provided for the evaluation of object instance search and localization in large scale videos. It consists of 146 ground truth video clips with bounding box annotations of object instances in each frame. The total download size of the videos is ~222MB.

Distractor videos used in the experiments from Stanford I2V are not included, but can be accessed here:

Content and Format

Besides a readme file, the dataset includes three folders:


./queries/: 10 query object instances, each in .jpg format
./gt_videos/: 146 .mp4 ground truth videos, resolution 800x400. Each video is named after the ground truth object it contains + a number. e.g. ferrari1.mp4. If a video contains multiple objects, it is named by concatenating individual object names with an underscore, e.g. kittyb3_kittyg3.mp4
./gt/: 151 ground truth annotations. Each .gt file is named after its corresponding video file. If a video contains > 1 object instances, it will spawn multiple .gt files, one for each object. e.g. kittyb3_kittyg3.mp4 is associated with both and
format of .gt:
1st row: duration of the object instance (in terms of #frames)
2nd row onwards: frm_idx top left bottom right (frm_idx starts from 0)
