4. 2003.04.02 - SLIDE 4IS246 - SPRING 2003 What is the Problem? Today people cannot easily find, edit, share, and reuse media Computers don’t understand media content –Media is opaque and data rich –We lack structured representations Without content representation (metadata), manipulating digital media will remain like word- processing with bitmaps

5. 2003.04.02 - SLIDE 5IS246 - SPRING 2003 Desiderata for Media Metadata At least, Pat should be able to use Pat’s metadata Better, Chris should be able to use Pat’s metadata Even better, Chris’s computer should be able to use Pat’s metadata At best, Chris, Pat, and their computers should be able to use the metadata they all produce

6. 2003.04.02 - SLIDE 6IS246 - SPRING 2003 Representing Video Streams vs. Clips –Stream-based annotation makes annotation pay off The richer the annotation, the more numerous the possible segmentations of the video stream Clips change from being fixed segmentations of the video stream, to being the results of retrieval queries based on annotations of the video stream Annotations create representations that make clips, not representations of clips Video syntax and semantics –The Kuleshov Effect –Video has a dual semantics Sequence-independent invariant semantics of shots Sequence-dependent variable semantics of shots Ontological issues in video representation –Video plays with rules for identity and continuity Space Time Person Action

7. 2003.04.02 - SLIDE 7IS246 - SPRING 2003 The Search for Solutions Current approaches to creating metadata don’t work –Signal-based analysis –Keywords –Natural language Need standardized metadata framework –Designed for video and rich media data –Human and machine readable and writable –Standardized and scaleable –Integrated into media capture, archiving, editing, distribution, and reuse

8. 2003.04.02 - SLIDE 8IS246 - SPRING 2003 Signal-Based Parsing Effective and useful automatic parsing –Video Scene break detection Camera motion analysis Low level visual similarity Feature tracking –Audio Pause detection Audio pattern matching Simple speech recognition Approaches to automated parsing –At the point of capture, integrate the recording device, the environment, and agents in the environment into an interactive system –After capture, use “human- in-the-loop” algorithms to leverage human and machine intelligence

9. 2003.04.02 - SLIDE 9IS246 - SPRING 2003 Why Keywords Don’t Work Are not a semantic representation Do not describe relations between descriptors Do not describe temporal structure Do not converge Do not scale

10. 2003.04.02 - SLIDE 10IS246 - SPRING 2003 Natural Language vs. Visual Language Jack, an adult male police officer, while walking to the left, starts waving with his left arm, and then has a puzzled look on his face as he turns his head to the right; he then drops his facial expression and stops turning his head, immediately looks up, and then stops looking up after he stops waving but before he stops walking.

11. 2003.04.02 - SLIDE 11IS246 - SPRING 2003 Notation for Time-Based Media: Music

12. 2003.04.02 - SLIDE 12IS246 - SPRING 2003 Visual Language Advantages A language designed as an accurate and readable representation of time-based media –For video, especially important for actions, expressions, and spatial relations Enables Gestalt view and quick recognition of descriptors due to designed visual similarities Supports global use of annotations

13. 2003.04.02 - SLIDE 13IS246 - SPRING 2003 After Capture: Media Streams

14. 2003.04.02 - SLIDE 14IS246 - SPRING 2003 Media Streams Features Key features –Stream-based representation (better segmentation) –Semantic indexing (what things are similar to) –Relational indexing (who is doing what to whom) –Temporal indexing (when things happen) –Iconic interface (designed visual language) –Universal annotation (standardized markup schema) Key benefits –More accurate annotation and retrieval –Global usability and standardization –Reuse of rich media according to content and structure
