  1. Data Set and Ground Truth

  2. Data set and Ground truth • Data set contents • Data set resources • Ground truth contents • Ground truth resources

  3. Data set contents Goal: Capturerealisticvideo sequences with graduate difficulties: • lighting variations, • occlusions … covering predefined scenarios.

  4. Data set contents Video providers, main characteristics • Inrets: Building Entrance, Indoor/Outdoor, Multi-view • CEA: Corridor + Road, Indoor/Outdoor, Visible/IR • RATP: Metro, Indoor, Crowded environment • iLids: Road, Outdoor, Real street context • Silogic: Aircraft parking zone, Multi-view

  5. Data set contents 5 Topics • Apron • Building Corridor • Building Entrance • Metro • Road

  6. Data set contents 2 points of view APRON Different weather conditions

  7. Data set contents BUILDING CORRIDOR Visible and IR clip

  8. Data set contents BUILDING ENTRANCE Entrance and Car Park 4 points of view

  9. Data set contents METRO Real subway scene

  10. Data set contents ROAD Visible and IR clip Real scene

  11. Data set and Ground truth • Data set contents • Data set resources • Ground truth contents • Ground truth resources

  12. Data set resources

  13. Data set resources

  14. Data set resources

  15. Data set resources • 2 video data set (test + evaluation) • 2*2 DVD provided • Documentation (metrics, annotation rules, structures and formats) • Context and calibration information • Data base (xls file)

  16. Data set resources

  17. Data set and Ground truth • Data set contents • Data set resources • Ground truth contents • Ground truth resources

  18. Ground truth contents • Context information • Physical objects of interest and events annotation Annotation rules provided to participant in a document and updated during the project Examples…

  19. Data set and Ground truth • Data set contents • Data set resources • Ground truth contents • Ground truth resources

  20. Ground truth resources

  21. Conclusion & Feedback Difficulties encountered: • Definition of event • Annotation subjectivity Proposition for other evaluation project: • Ground truth done before data set distribution: Easier to identify difficulties that may encountered participants and add explanations and specific annotation rules • Ground truth given between the deadline submission and the results processing to be able to correct ground truth before evaluation -> Time consuming
