  1. 1. Current Image Processing Technology <br />for Holographic Imaging<br />PojNetsiri, PhD<br /><ul><li>Algorithms to convert 3D images to hologram</li></ul> - Raster image<br /> - Vector image<br /><ul><li> Original image acquisition system</li></ul> - 16-cameras system<br /><ul><li> Multiple objects in 1 hologram
  2. 2. Hologram from stereo cameras</li></li></ul><li>Raster images:<br />Example:<br />3D Brain Magnetic Resonance Imaging<br />Hologram<br />
  3. 3. 3D data<br />30 Perspectives<br />Camera<br />Polymer material<br />Hogel (Holographic Element) <br />
  4. 4. Magnetic Resonance Angiography:<br />Hologram<br />
  5. 5. Raster images:<br />16 Perspectives from 16 Cameras<br />1<br />3<br />4<br />5<br />6<br />7<br />8<br />2<br />9<br />10<br />11<br />12<br />13<br />14<br />15<br />16<br />
  6. 6. Vector images: CAD, Animation<br />
  7. 7. Original image acquisition system: <br /> -16-cameras system<br />16 cameras<br />Hologram<br />
  8. 8. Camera System<br />Images<br />
  9. 9. Red<br />Red Hogel<br />Color Hologram<br />Green<br />Green Hogel<br />Blue<br />Blue Hogel<br />
  10. 10. Special effects: Multiple objects in one hologram <br />Object1<br />Object2<br />
