  1. ETISEO Annotation rules • Data structure • Annotation tool and format • Ground truth creation rules • Reference data generation

  2. Data structure - context • Context • Id • Type (ex: zone) • Name (ex: exit_zone) • Polygon

  3. Data structure - object • Physical object • Id • Start time • Type (ex: person, vehicle…) • Subtype (ex: car, van…) • Info2D • Info3D • Links • Speed • GT Nature • GT Status • GT Occluded (partially or completely) • GT Connected with • GT : specific to annotation purpose

  4. Data structure - event • Event • Id • Name • Start and end time • Status • Involved objects (physical object of interest and contextual object)

  5. ETISEO Annotation rules • Data structure • Annotation tool and format • Ground truth creation rules • Reference data generation

  6. Annotation tool and format • Annotation delivered with video: • Database - Excel file • Context annotation - Viper-GT tool and format • Annotation delivered at the end of Etiseo: • Ground truth - Viper-GT tool and format • Reference data (computed from GT) – Specific tool and Viper-GT format

  7. Annotation tool and format

  8. Annotation tool and format • Viper-GT format example • <?xml version="1.0" encoding="UTF-8"?> • <viper xmlns="http://lamp.cfar.umd.edu/viper#" xmlns:data="http://lamp.cfar.umd.edu/viperdata#"> • <config> <…> • </config> • <data> • <sourcefile filename="file:ETI-VS1-CR-4-C1.avi"> • <object framespan="1:100" id="4" name="physical_object"> • <attribute name="nature"> • <data:svalue value="physical_object_of_interest"/> • </attribute> • <attribute name="type"> • <data:svalue value="person"/> • </attribute> • <attribute name="info2D"> • <data:bbox framespan="1:1" height="182" width="86" x="138" y="59"/> • <data:bbox framespan="2:2" height="183" width="86" x="139" y="59"/> • <data:bbox framespan="3:3" height="185" width="86" x="141" y="60"/> • <data:bbox framespan="4:17" height="187" width="87" x="143" y="60"/> • <…> • <data:bbox framespan="40:100" height="212" width="10" x="3" y="10"/> • </attribute> • <…> • </sourcefile> • </data> • </viper>

  9. ETISEO Annotation rules • Data structure • Annotation tool and format • Ground truth creation rules • Reference data generation

  10. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  11. Ground truth creation – Rules for objects • Contextual object • Annotated during its period of movement

  12. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  13. Ground truth creation – Rules for objects • Static physical object of interest • Any physical object of interest is annotated on the whole video clip (ex: a parked vehicle) • First frame and last frame of a video clip

  14. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  15. Ground truth creation – Rules for objects • Occlusions – general rules • Apparition of an object: the BBox increase with object apparition including only its visible part, • All BBox are limited by the image boundary, • Partial and complete occlusion will be differentiate in the evaluation (attribute “occluded”).

  16. Ground truth creation – Rules for objects • Static occlusions (by a contextual object) • Partial occlusion: full BBox is drawn including hidden part,

  17. Ground truth creation – Rules for objects • Static occlusions (by a contextual object) • Complete occlusion - two cases: • all “escapes” of the contextual object are visible: full BBox is drawn all the time,

  18. Ground truth creation – Rules for objects • all “escapes” of the contextual object are not visible: the object is no more annotated when completely occluded

  19. Ground truth creation – Rules for objects • Dynamic occlusion (by another object) • Partial or complete occlusion: in both cases, the full BBox is drawn including hidden part.

  20. Ground truth creation – Rules for objects • Split object due to occlusion • A unique BBox including all sub part is drawn.

  21. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  22. Ground truth creation – Rules for objects • Artefacts • Only the part constituting the objects forms the BBox, artefacts (shadow, reflection…) are ignored for instant. • Annotated in video data set 2

  23. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  24. Ground truth creation – Rules for objects • Sudden illumination changes (tagged frames) • Static object • Object in movement: position interpolation

  25. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  26. Ground truth creation – Rules for objects • Held object • The holder and the held object are both annotated (if visible), • The carried object is connected to the holder. • Example: bag-person, person-bike, door-vehicle

  27. Ground truth creation – Rules for objects • Specific case • Person getting in/out a vehicle: annotated only when visible

  28. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  29. Ground truth creation – Rules for objects • Group - Crowd • Group: multiple bounding boxes (persons + group) • Crowd : unique Bbox when individual annotation is impossible.

  30. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  31. Ground truth creation – Rules for objects • Crowded video clip • Only object involved in event of interest are annotated. No false detections evaluation

  32. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  33. Ground truth creation – Rules for objects • Multi-view annotation

  34. Ground truth creation rules • Rules for objects: • Contextual object • Static physical object of interest • Occlusion • Artefacts • Sudden illumination changes • Held object • Group - Crowd • Crowded video clip • Multi-view annotation • Rules for events

  35. Ground truth creation – Rules for events • Event – data structure • Id • Name • Start and end time • Status • Involved objects: • Id of the physical object of interest in GT files • Id of the contextual object in context information files

  36. Ground truth creation – Rules for events • Choice of event for each video clip in the event ontology => defined in the database xls file (provided with video)

  37. Ground truth creation – Rules for events • Automatic annotation of events with quantitative constraints, example: • Related to kinematics properties: stopped, running… • Related to spatial properties: close_to, inside_zone… • Manual annotation of other events: holding, pushing, waiting, gets_in/out,…

  38. Ground truth creation – Rules for events • Example

  39. ETISEO Annotation rules • Data structure • Annotation tool and format • Ground truth creation rules • Reference data generation

  40. Reference data generation • Filtering on object size • Object speed computation • Group generation • Multi-view and 3D reconstruction • Events with quantitative constraints generation
