Pupil tracking technology based on hybrid cameras for sub-holographic display

• Pupil-tracking technology based on hybrid camera uses a depth camera and a
  stereo camera with different resolution and characteristics to find the location
  of pupil and eye. This can be performed by combining the analyzed face
  detection result and eye recognition result on each image.
• It is possible to receive an image from the camera, calculate the tracking results
  in real time, show screen printing, and transmit the coordinates of the pupils to
  the sub-hologram display.
