Datasets

• Middlebury 2009 paper
  • 8 image pairs for training, with ground truth flows generated using four different techniques
  • Displacements are very small, typi- cally below 10 pixels.
• KITTI 2012 paper
  • 194 training image pairs, large displacements, contains only a very special motion type
  • The ground truth is obtained from real world scenes by simultaneously recording the scenes with a camera and a 3D laser scanner.
  • Task: stereo, flow, sceneflow, depth, odometry, object, road, tracking, semantics, etc.
• MPI Sintel 2012 paper
  • 1041 training image pairs, ground truth from rendered artificial scenes with special attention to realistic image properties
  • Very long sequences, large motions, specular reflections, motion blur, defocus blur, atmospheric effects
  • Task: optical flow.
• Flying Chairs (Vision group, Uni-Freiburg) 2015 paper
  • 22872 image pairs, a synthetic dataset with optical flow ground truth
  • Task: optical flow.
• ChairsSDHom (Vision group, Uni-Freiburg) 2017 paper
  • Task: optical flow
  • Designed to be robust to untextured regions and to produce flow magnitude histograms close to those of the UCF101 dataset (small displacement, less than 1 pixel).
