  • Current Image Processing Technology
    for Holographic Imaging
    PojNetsiri, PhD
    • Algorithms to convert 3D images to hologram
    - Raster image
    - Vector image
    • Original image acquisition system
    - 16-cameras system
    • Multiple objects in 1 hologram
    • Hologram from stereo cameras
  • Raster images:
    Example:
    3D Brain Magnetic Resonance Imaging
    Hologram
  • 3D data
    30 Perspectives
    Camera
    Polymer material
    Hogel (Holographic Element)
  • Magnetic Resonance Angiography:
    Hologram
  • Raster images:
    16 Perspectives from 16 Cameras

  • Work in progress: Hologram from 2 cameras
    Too many cameras?
  • 2 cameras is BETTER
    Hologram
    Can be extended to
    Full-parallax using 4 cameras
  • Original Images from
    Fuji Film FinePix Real 3D
  • Corner and Edge Detection

  • + : corners from left image
    + : corners from right image
    Corner detection
  • 3D Feature reconstruction
  • Perspective Reconstruction
