augmented reality
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
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 constrain
    • user viewing method
ar systems
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
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 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.

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
