  1. Workshop in Media Authoring Automatic Generation of Animation and Video Contact Doron Friedman doronf@math.tau.ac.il Mobile: 054-461807 Intelligent Tools for Media

  2. Agenda • Introduction • Motivation and Background • Course Material • Logistics and Administration • Description of Projects Intelligent Tools for Media

  3. Motivation – Media Authoring • 3D: • Professional animators – several years of study • Professional software • Low leve of abstaction • Very little reuse • Video • Professional editors • Professional software • Pixel based (rather than object based) Intelligent Tools for Media

  4. Smart Graphics • What this is NOT about • How to achieve efficient 3D rendering • What this IS about • How to quickly generate animation from high level input Intelligent Tools for Media

  5. Making movies (Simplified) Story/idea Script Shooting Script Animation File • Story- understanding • Storytelling • Directing • NLU • Reusable animation • Animation composition • Text-to-speech • Theory of space and time • Camera-control principles • Model of actions Intelligent Tools for Media

  6. Script -> Animation Formal Script Shooting Script Animation File • Reusable animation • Animation composition • Text-to-speech • Theory of space and time • Camera-control principles • Model of actions Intelligent Tools for Media

  7. Interactive Virtual Environments • Linear Animation • Authoring • Interactive Virtual Environments • Authoring • Agent • Real-time Director Intelligent Tools for Media

  8. Production Industry Rapid prototyping Storyboarding Gaming Industry Engine for interactive games A movie-maker game Toys (Lego/AIBO) Education Training Simulations Industrial Military Traffic Scientific Medical Applications Intelligent Tools for Media

  9. State of the trade today • Leading tools (Maya, RenderMan, ..) • Leading standards/trends (VRML, Java3D, …) • How authors work today Intelligent Tools for Media

  10. SMIL-1 - • Layout • Relative/absolute positioning • Z-index • Fit (meet, slice, scroll) • Time • Par • Seq • begin Intelligent Tools for Media

  11. SMIL-2 • 45 Modules / Language Profiles • Integration with other languages • Vector graphics • Excl (exclusive par) • Relative synchronization • Time manipulation (speed, reverse) • Animation • AudioLayout • Transitions Intelligent Tools for Media

  12. MPEG-4 as a Rich Media Representation Scheme • Several goals • Profile Approach Intelligent Tools for Media

  13. Mpeg-4 Relevant Features • TermCap node: • Frame rate • Memory/CPU load • BIFS switch node Intelligent Tools for Media

  14. MPEG-7 – the Bits about the Bits • D – Descriptors – representation of features (syntax + semantics) • DS – Description Schemes – structure and semantics of relationships between components • DDL – Description Defintion Language – to create new DS, and perhaps new D Intelligent Tools for Media

  15. Example – Multiple Description Types • Structural – right, left, moving towards • Physical – color, shape, motion • Conceptual – goalkeeper, player, ball Intelligent Tools for Media

  16. MPEG-21 • Define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices • 7 Items • Digital Item Declaration • Digital Item Identification and Description • Content Handling and Usage • Intellectual Property Management and Protection • Terminals and Networks • Content Representation • Event Reporting Intelligent Tools for Media

  17. Course Material • Background: OO Design and Programming (C++/Java, tbd) • 3D technologies: • VRML • HANIM • Java3D ? • MPEG-4/BIFS/XMT • Video/Mixed Technologies • MPEG-4 • JMF • SMIL-1/SMIL-2 Intelligent Tools for Media

  18. Course Logistics • Communication channels • Groups • Development methodology • Dates Intelligent Tools for Media

  19. Communication Channels • Mailing list: tba • Web-site: http://www.math.tau.ac.il/~doronf/workshop_2002.html Includes links to resources • My e-mail: doronf@post.tau.ac.il Intelligent Tools for Media

  20. Groups • 1-4 people in group (recommended: 2) • Group gets one grade • Inter-group integration – big bonus! Intelligent Tools for Media

  21. Development Methodology • Some thoughts on Software Engineering: • Writing programs is easy, writing software is impossible • % of code used • Legacy software Intelligent Tools for Media

  22. Development Process (waterfall) • MRD (Marketing Requirements Document) • HLD (High Level Design) • FRS (Functional Requirement Specification) • ATP (Acceptance Testing Procedures) • Code • Debug • Testing / Q.A. Intelligent Tools for Media

  23. Projects • Animation Library • Automatic Summaries • Video Template Authoring • Object-based Video • Film & TV School projects Intelligent Tools for Media

  24. Animation Library • Objects with animation • Humanoid • Car • Door • 4-legged animal • Elevator • Bottle, glass and drink • Cigarette and smoke • Weapons • … Intelligent Tools for Media

  25. Stand Walk (from, to), (path) Run Jump Sit (on) take (object) Put (object, location) Touch (object/organ) Wave Talk Eat/drink Climb (wall, stairs,..) Animation Library - Humanoid Intelligent Tools for Media

  26. Animation Library - Car • Drive (from, to), (path) • Open (door) • Close (door) • Traffic simulation Intelligent Tools for Media

  27. Animation Library - Speech • Text-to-speech • Lip animation (sync?) Intelligent Tools for Media

  28. Animation Library – Facial Expressions • Basic emotions (smile, angry, afraid) • Low level animation • Eyes (look-at, close, open, blink) • Eye-brows • Mouth • Face features (hair color, hair style, eye color, glasses) Intelligent Tools for Media

  29. Animation Library - Other • Door (open, close) • 4-legged (share animation with humanoid) • Elevator (open, close, go-to-floor) • Bottle, glass, drink (pour, person drinking, spill) • Gun (shoot, bullet/missile) • … Intelligent Tools for Media

  30. Animation Composition • Sequence (states) • Parallel • (walk, run, Jump) x (hold, wave) • Compound Animations (hierarchy) • E.g: eat = take (food), touch(mouth) • Inverse Kinematics Intelligent Tools for Media

  31. Smart Objects • Different Complexity Levels of Behavior • Default behaviors • Rules and constraints (trigger -> action) • Behavior model (perception, motivation, planning) • High level interface to expose capabilities • Naïve physics • Examples • Avatar • Tamaguchi/pet • Car • Elevator Intelligent Tools for Media

  32. Problem specification -example Smart lift in crowd simulation Intelligent Tools for Media

  33. Defining object behaviors - example • smart table in party simulation • graspable fruits • get_closest_ fruit (and eat it) • replace_fruits Intelligent Tools for Media

  34. Script Parsing • Define syntax • Define internal representation • Parse input, create representation, and write to file • Challenges • Action • Space (near, behind, path planning, obstacles) • Time (before, after, concurrent, fast) Intelligent Tools for Media

  35. Along Example Intelligent Tools for Media

  36. Animation Generation • Define internal representation • Read representation from file • Generate VRML • Challenges • Re-use VRML code • Performance and optimization • scalability Intelligent Tools for Media

  37. Automatic Editing • Formalize cinematic principles • Analyze screenplay • Hints (Annotations) in screenplay • Editing • Separate into shots • Decide shot type • Camera motion • Light • Sound • Dissolves • Effects Intelligent Tools for Media

  38. The Line External External Internal Apex Example - shots Camera placement Intelligent Tools for Media

  39. Examples • http://www.math.tau.ac.il/~doronf/se-anim_files/frame.htm Intelligent Tools for Media

  40. Template-based Video Editing Intelligent Tools for Media

  41. DOM Abstract Template XML XSL material 1…. XSL XSL material n SMIL-1 MPEG-4 caching DB caching Automated template-based generation • Wizard approach: user fills in the slots • Performance: static elements of presentation are pre-cached (unless very large) • Allows for dynamic, on-the-fly generation of presentations Intelligent Tools for Media

  42. Rich Media Transcoding Intelligent Tools for Media
