  1. FYP Project LYU0301:Secure and Reliable PDA-Based Communication System

  2. Secure and Reliable PDA-Based Communication System • Abstract • Design and develop a PDA-based communication system for a group of workforce (e.g. Police) • The communication content should be secured. • The system can be executed over 72 hrs (at least) without crash. • Fault tolerant measures on both the client and server sides. • All the information should still be consistent after failure. • Unauthorized users cannot access the content

  3. Secured and Reliable PDA-Based Communication System

  4. Secured and Reliable PDA-Based Communication System • Techniques: • Server load balancing • Embedded systems programming • Bluetooth or 802.11b • Encryption and security

  5. Symbian-based Mobile Tour Guide System • Abstract • Develop an interactive tour guide system using the Symbian OS (e.g. Nokia 3650…) • The system should equips multimedia presentation capabilities. • Making use of messaging systems: MMS and SMS. • Making use of the camera function of modern mobile phone devices • Location sensitive elements can be added

  6. Symbian-based Mobile Tour Guide System Virtual Tour Guide Multimedia Presentation Camera Navigation

  7. Symbian-based Mobile Tour Guide System • Technique • Native Symbian programming in C++. (Beware! Symbian OS is very tough to learn.) • Multimedia processing • Mobile Messaging • Location sensitive services

  8. Symbian-based Mobile Tour Guide System • Technique • Native Symbian programming in C++. (Beware! Symbian OS is very tough to learn. Pick this project only if you want to face the most challenging work in modern mobile device programming.) • Multimedia processing • Mobile Messaging • Location sensitive services

  9. FYP Project LYU0302:PVCAIS – Personal VideoConference Archives Indexing System

  10. LYU0302: PVCAIS-Personal Video-Conference Archive Indexing System • Background • Videoconference is becoming popular • Participants wish to keep videoconference archives for the later reference • Normal video and audio files are neither searchable nor helpful to recall their contents • Indexing of videoconference archives has not been investigated till now

  11. LYU0302: PVCAIS • Objective: develop an experimental system with the following architecture.

  12. LYU0302: PVCAIS • Project tasks 1. Study the mechanism and media format of a videoconferencing client to receive data.

  13. LYU0302: PVCAIS • Project tasks 2. Select a group of algorithms to implement the multimedia-indexing functions. 3. Integrate these functions to generate an XML index file for each videoconference. 4. Create and manage the file system of indexed archives.

  14. LYU0302: PVCAIS • Project tasks 5. Implement a GUI of PVCAIS to provide the searching and browsing functions of indexed videoconference archives. Searching Browsing Figure 4. An example GUI of PVCAIS

  15. FYP Project LYU0303: Video Object Tracking and Replacement for Post TV Production 15

  16. Augmented Reality • Augmented Reality (AR) is a form of human-machine interaction where information is presented in the file of view of an individual • augmenting the real world scene necessitating that the user maintains a sense of presence in that world. • the virtual images are merged with the real view to create the augmented display. • technology for merging the real and virtual image streams in tight constrain.

  17. AR (movie)

  18. AR Animation (movie)

  19. Key Technologies of AR • accurate registration of the virtual objects with the real world image • camera position, viewing parameters • digital composition, scene lighting, object texture mapping • real-time processing constraint • user viewing method

  20. Three Classes of AR Systems • Monitor Based Augmented Reality • Video See-through Augmented Reality Display • Optical See-through Augmented Reality Display

  21. AR using Monitor (movie)

  22. AR using Head Mount Device (movie)

  23. ARCADE: Augmented Reality Computing Arena for Digital Entertainment • AR provides new ways of digital entertainment possibilities when combining with traditional entertainment channels. • Key applications: TV and Movie productions combining fantasy with reality

  24. LYU0303: Video Object Tracking and Replacement for Post TV production • Design the special pattern markers for 3D objects to be applied on objects during the video shooting • Develop efficient algorithm to calculate the object’s positions and orientations in the video • Non real-time algorithm • MPEG-1 or DV quality video • The special pattern marks and the detection algorithm must survive from the partial occlusion of the object.

  25. LYU0303: Video Object Tracking and Replacement for Post TV production • Develop algorithm to determine the lighting condition of the scene in a video • Generate realistic images to replace the video object according to it’s positions and orientations • non real-time algorithm • MPEG-1 or DV quality video • Simple object, soda can or cereal box • The algorithm must survive from the partial occlusion of the object • Photometric registration problem

  26. Popular 2D Markers

  27. Illustration of possible Special Pattern Markers for 3D Object

  28. Same Object with Two Brand Names
