What?

  • Kinect@Home have collected nearly 1000 RGB-D video

recordings from users all around the world

  • We have selected 54 of these recordings to be released

as the first dataset

Why?

  • Algorithms are getting better
  • It is time to give them better challenges
  • Recordings made in-house are biased
  • Crowdsourcing provides real world data with less bias

How?

  • Data collection needs to be simple for the users
  • Users need a reason to collect data = motivation

What about ground truth?

  • There is no ground truth
  • ...but the dataset is still useful!

How can it be used?

  • By comparing different algorithms
  • Kinfu vs. key point based (SURF) pose estimation
