  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

  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
