1. 2007/2008 Semester 1 SD5943 Multimedia Literacy Week03 – An old concept with new technologies Prepared by Wilson YUEN [sdwilson@polyu.edu.hk]

2. Agenda • Introduction • An old concept with new technologies, applied in the following sections: • Text • Audio • Graphics • Animation • Video/Movie • Interactivity • Conclusion

3. Introduction (1) • An evolution of the digital technologies in last two decades initiates a great demand and opportunity to revamp the old media. • From digitalizing and recovering analog contents to using advanced digital technologies to retake the old titles of film/movie, all those activities driven the demand and development of sophisticated digital technologies. • According to Moore’s Law, “…the complexity of integrated circuits, with respect to minimum component cost, doubles every 24 months…”, implies the momentum of using and developing new digital technologies will keep non-stop.

4. Introduction (2) • E.g. #1 Mission Impossible (1966-1973 & 1996-2006) http://www.youtube.com/watch?v=_YWD0YGbr-Y

5. Introduction (3) • E.g. #2 King Kong (1933, 1976 & 2005) Digital effects by Weta Digital Ltd.

6. Introduction (4) • E.g. #3 英雄本色 (1967 & 1986)

7. Introduction (5) • E.g. #4 Super Mario (1985-2007) http://en.wikipedia.org/wiki/Mario

8. Text • From traditional script writing to nowadays – collaborative computing. It is a great change about the mode of creation. • In the analysis and promotion of web-technology, the phrase Web 2.0 refers to a perceived second generation of web-based communities and hosted services — such as social-networking sites, wikis and folksonomies — which aim to facilitate collaboration and sharing between users. • The term became popular following the first O'Reilly Media Web 2.0 conference in 2004, and has since become widely used.

9. Audio (1) • From Phonograph record (Gramophone record), Cassette tape, Laserdisc (LD), Sony Minidisc Data (MD), Compact Disc (CD) to MP3  From analog storage to digital storage.

10. Audio (2) • From analog, low-fidelity digital to high-fidelity digital audio system. Same title of song from same singer can be published twice or even more times, just with different quality (upgrade from 16 Bits to 24 Bits of AD digitalization) or medium.

11. Audio (3)

12. Graphics (1) • From traditional Chinese painting to the advanced Computer-generated imagery (CGI), all are the combinations of tools, techniques and design. • Can we applied advanced computer graphics technologies to manipulate the traditional Chinese art works?

13. Graphics (2) • Animating Chinese Landscape Paintings • Ref.: http://www.cse.ust.hk/~cpegnel/ACLP/thesis.html • Digital Chinese Arts • Ref.: http://www.cse.ust.hk/~cpegnel/VCB/

14. Graphics (3) • Computer Vision • Computer vision is the science and technology of machines that see. • As a scientific discipline, computer vision is concerned with the theory and technology for building artificial systems that obtain information from images. The image data can take many forms, such as a video sequence, views from multiple cameras, or multi-dimensional data from a medical scanner.

15. Graphics (4) • As a technological discipline, computer vision seeks to apply the theories and models of computer vision to the construction of computer vision systems. Examples of applications of computer vision systems include systems for: • Controlling processes (e.g. an industrial robot or an autonomous vehicle). • Detecting events (e.g. for visual surveillance) • Organizing information (e.g. for indexing databases of images and image sequences), • Modeling objects or environments (e.g. industrial inspection, medical image analysis or topographical modeling), • Interaction (e.g. as the input to a device for computer-human interaction).

16. Graphics (5)

17. Animation (1) • CMU, Virtual reception – Roboception (by 3D character and animation).

18. Animation (2) • Japan First Virtual Idol – DK96 (by 3D character and animation).

19. Animation (3) • Virtual Fitting

20. Animation (4) • Bodybush – by Prof. Horace Ip (CityU) http://aimtech.cityu.edu.hk/bodybrush/

21. Animation (5) • Smart Ambience Therapy (SAT) – by Prof. Horace Ip (CityU) http://aimtech.cityu.edu.hk/sat/

22. Animation (6) • Playmotion

23. Video/Movie (1) • From the analog Standard Definition (SD) to digital High Definition (HD). • From the analog 35mm film to digital cinema with 2K & 4K resolution (2K and 4K refer to images with 2048 and 4096 horizontal pixel resolution). • Any changes with the concept of Television and Film/Movie? • Some new terms were coined, such as Interactive TV or 4D Movie.

24. Video/Movie (2) • Multi-camera (Camera Array)

25. Interactivity (1) • Digital Entertainment adopted of most advanced 3D graphics, Artificial Intelligence (AI) and ICT technologies. • The evolution of computer graphics from 2D to 3D make the development of new game titles with traditional characters become possible. • Certain very famous game characters have been published in different titles by using different technologies over 20 years. • Sonic the Hedgehog (1991 – 2005) • Super Mario (1985 – 2007) • Pac Man (1982 – 2006)

26. Interactivity (2) • Besides, the technologies of the controller also make great influence to the development of the game titles.

27. Conclusion • It is no matter old or new concept, applying of new technologies with old concept can be a new trend of the digital revolution. • Digital technology innovation not only relies on the development of hardware and software technologies, but also the contents. • “Design” make a critical step to drive the development of – “Apply an old concept with new technologies”
