  1. FYP Project LYU0303: Video Object Tracking and Replacement for Post TV Production 1

  2. 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.

  3. AR (movie)

  4. AR Animation (movie)

  5. 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

  6. AR Systems • Monitor Based Augmented Reality • Video See-through Augmented Reality Display • Optical See-through Augmented Reality Display

  7. AR using Monitor (movie)

  8. AR using Head Mount Device (movie)

  9. 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

  10. 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.

  11. 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

  12. Popular 2D Markers

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

  14. Same Object Two Brand Names
