This webpage provides datasets for spatiotemporal grouping. The dataset contains 11 image sequences that depict a wide range of juxtaposed spatiotemporal patterns, including motion, static (stationary texture), pseudo-transparency, translucency, temporal flicker, unstructured and various additional dynamic textures. The image sequences were acquired using a Canon HF10 consumer camcorder with capture rate of 30fps. Each image sequence is provided with a manually constructed groundtruth that delineates boundaries between distinct spatiotemporal regions.

For details of our technical approach to spacetime structure grouping, see our project page.


InputGround Truth
Example 1: Tree in foreground (static structure) being coarsely stabilized by moving camera operator with resulting background motion (motion structure).

Example 2: A painting (static structure) hanging on a blank wall (unstructured) with a light flickering in an adjacent hallway (temporal flicker structure).

Example 3: A duck swimming (motion structure) over turbulent water (dynamic texture structure).

Example 4: A person walking behind a fence (pseudo-transparency structure) with a stationary surround of fence, grass and trees (static structure).
