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

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

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

• Project tasks
• 5. Implement a GUI of PVCAIS to provide the
  searching and browsing functions of indexed
  videoconference archives.

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.

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

Three Classes of AR Systems

• Monitor Based Augmented Reality
• Video See-through Augmented Reality Display
• Optical See-through Augmented Reality Display

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

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
  objects 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 its 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
