Dataset

Datasets are split into train, val and test set. Every line is a self contained JSON string (ndJSON).

Scene:

{"scene": {"id": 266, "p": 254, "s": 10238, "e": 10358}}

Track:

{"track": {"f": 10238, "p": 248, "x": 13.2, "y": 5.85}}

with:

• id: scene id

• p: pedestrian id

• s, e: start and end frame id

• f: frame id

• x, y: x- and y-coordinate in meters

Frame numbers are not recomputed. Rows are resampled to about 2.5 rows per second.
