About

Action analysis and recognition is a very active research topic. The research group of the Mobile Robotics Laboratory from the Institute of Systems and Robotics, University of Coimbra releases the University of Coimbra 3-D Motion Database (UC-3D) so to promote this research. The database was developed in the context of an Action-based Person Recognition research work, for which it is also found suitable for research on action-based biometrics.

Available data types encompass high resolution Motion Capture, acquired with MVN Suit from Xsens and Microsoft Kinect RGB and depth images. This diversity intents to provide the community with an homogeneous dataset for fair comparison between methods using different datatypes.

In the UC-3D Motion Database researchers will currently find 11 different activities, performed by 13 different actors. 6 of these actions are interactive, containing 2 different persons, for which the MVN data is only recorded for one of them. Each person performs 3 trials for each different action. Typical action duration is 3 seconds.

Structure

The database is composed of 3 different data types, stored using ZIP compression, where the format of a file name is 'ddd-aaa-ppp.zip' and:

ddd - data type which can be:

  • RGB – RGB images

  • DEP – DEP images

  • MVN – XML file containing information for the 17 Inertial Measuring Units of the MVN suit

    With respect to the XML with the MVN data, it contains data as in the following example:

    <mvnxInfo
        frameCount="419"
        frameRate="120"
        segmentCount="23"
        recDate="1375790676.105"
        originalFilename="MVN-BND-p01.mvn"
        velData="1"
        accData="1"
        angVelData="1"
        angAccData="1"
    />
                                                

aaa - performed action:

  1. BND – bend

  2. CNV – conversation (2 person interaction)

  3. HSH – handshake (2 person interaction)

  4. HUG – hugging (2 person interaction)

  5. JMP – Jumping

  6. PCH – Punching (2 person interaction)

  7. PCD – punched (2 person interaction)

  8. PSH – Pushing (2 person interaction)

  9. RUN – Running

  10. WLK – Walking

  11. SIT – Sitting/Standing Cycle

ppp - enumerated from p01 to p13:

identifies main actor, whose MVN is captured for.


Download

Remark 1: data for p10 to p13 will be uploaded soon.

Remark 2: RGB data for the conversation action will be uploaded soon, due to filesize dimensions (+1.5GB).

Remark 1: These actions were acquired under the scope of the Prometheus project.
