LOITER DATASET

The dataset is created from a synthetic surveillance dataset. The scene contains eight cameras, each with a 1920x1080 resolution. The footage shows actors moving across the area. They do not stop, turn around, or change their trajectory. One of the actors acts like a loiterer. While the actor does not stop or show an unusual trajectory, they repeatedly appear on the different cameras. From this scene, facial features were extracted. These facial features were then grouped together using the Luigi indexing method descibed in [1,2], and the visualized result of the loitering discovery system described in [3]. This dataset contains the metadata of these features.

Format Description

The dataset is a .txt file. Each line contains the metadata of one facial feature Groups of facial features are seperated with a dash -

Each feature has the following format:

UniqueID CameraID BeginTimestamp FrameID FrameRate Left Top Right Bottom

Example:

9310 3 1446038202 2142 29.970 567 320 643 412
  • UniqueID: Unique identifier of the feature.
  • CameraID: Identifier of the camera the feature was extracted from
  • BeginTimestamp: Timestamp of start of the video footage (Unix Epoch time)
  • FrameID: Number of frames since the start of the video footage
  • FrameRate: Frame rate of the video camera
  • Left: Bounding box top left X coordinate of the feature
  • Top: Bounding box top left Y coordinate of the feature
  • Right: Bounding box bottom right X coordinate of the feature
  • Bottom: Bounding box bottom right Y coordinate of the feature

The timestamp of a feature can be calculated as follows:

BeginTimeStamp + (FrameID / FrameRate)

The center of a feature can be calculated as follows:

Center X = Left + (Right - Left) / 2
Center Y = Top + (Bottom - Top) / 2

Here is a tiny sample of the dataset.
