Computer Assisted Manufacturing

  1. 1. PISA Production, Indexing and Search of Audio-visual Material Computer Assisted Manufacturing Dieter Van Rijsselbergen, IBBT – MMLab – UGent
  2. 2. PISA - Overview Computer Assisted Design Search Engine Concept Indexing Script Editing Retrieval • Parse scenario Script Editing • Timecode based indexing • Shooting script editor • Geo-temporal reference • Storyboard • Taxonomy based indexing and search Abstract • Facetted search Information Virtual Intelligent Analysis and Model Driven Development: Modelling Analysis Quantization • Setting (Stage properties, light) Interpretation • Character • Character identification • Synthetic Speech • Background categorisation • Sound effects Virtual and identification • Character animation Model • Topic and eventdetection • Virtual camera Quantization Computer Assisted Manufacturing Automated Reverse Engineering Realisation Production • Shot segmentation • Ingest Footage • Video footprint and reuse detection • Editing • Biometric face detection • Mastering • Background analysis • Reproduction to alternative distribution channels • Speech-to-text 35
  3. 3. Computer Assisted Manufacturing ! Computer Assisted Manufacturing is about automation of media production processes ! Based on extensive production metadata ! high level Product Engineering for narratives ! low level Manufacturing Engineering for actual manufacturing specifications ! Using clever algorithms to fill in the gaps ! supported by Trouvaille 36
  4. 4. Drama Manufacturing Processes Synopsis Dialogue Product Engineering Writing Writing Manufacturing Engineering Shooting 3-D Quality Editing Scripting Previsualization Assurance Manufacturing ? Acquisition ? ? 37
  5. 5. Objectives ! Extend manufacturing workflow with 3-D previsualization ! Build evolving products ! Re-use previsualization parameters during manufacturing ! Increase efficiency and automation in production processes ! 1) Rough Cut Editing based on 3-D previsualization ! 2) Repurposing for multiple output channels 38
  6. 6. Computer Assisted Manufacturing Rough Cut Editing
  7. 7. Rough Cut Editing ! Inclusion of 3-D previsualization into the drama manufacturing process ! Use previsualization as shooting script ! Integration into the MAMS and Craft Editing systems ! Building evolving products ! mixture of previsualized and shot footage ! evolve from all-previsualized to all-shot composition 40
  8. 8. Rough Cut Editing Processes Synopsis Dialogue Product Engineering Writing Writing Manufacturing Engineering 3-D Quality Editing Previsualization Assurance Manufacturing Previz. Acquisition Rendering 41
  9. 9. Computer Assisted Manufacturing Repurposing
  10. 10. Computer Aided Repurposing (CAR) ! Automated Repurposing of Drama ! Different output channels ! HDTV ! SDTV ! iPod/Cellular ! True Universal Media Experience ! requires semantically sensible scaling/cropping 43
  11. 11. Repurposing Concept ! Automated Repurposing of Drama ! Spatial adaptation using semantic Objects of Interest ! as in “focus on Capt. Kirk” ! decided by creative staff in function of the narrative ! is a form of Manufacturing Engineering ! can be defined in early 3-D Previsualization ! preparation not only of shooting script but also of adaptations ! parameters refined in Quality Assurance 44
  12. 12. Repurposing: How? ! 1) Determine where the semantic elements are ! Semantic Objects of Interest are linked with regions of interest ! manual annotation ! automated algorithms ! aided by Product Engineering metadata! Jenny Waldek 45
  13. 13. Repurposing: How? ! 2) Provide reframing instructions, e.g.: ! Object Orientation and Range ! “The Bad must be shown on the right…” 0.75 ! Object Size ! “… and I want it to be a full shot of The Bad.” Frame Size Object of Interest Size: (30%, 90%) 46
  14. 14. Repurposing: Channels ! HDTV ! Originally acquired high definition material ! SDTV ! Mobile (iPod) ! Legacy applications ! Semantically ! Common pan/scan repurposed ! Editing (AVID) 47
  15. 15. Repurposing Processes Synopsis Dialogue Product Engineering Writing Writing Manufacturing Engineering 3-D Repurposing Quality Scripting Editing Previsualization Assurance Manufacturing Previz. EDL Acquisition Repurposing Rendering Rendering 48
