The invention relates to fast processing techniques designed for enhancing the pictorial contents of digital holograms, without the need to reconstruct the original 3D scene. The hologram is back-projected to a hypothetical 2D image known as virtual diffraction plane (VDP). The VDP is then processed.....

When a 2D image is displayed on a 3D (autostereoscopic) monitor, its resolution is significantly degraded. To overcome this problem, CityU developed an active barrier that converts a 2D display device into a 3D display device. The invention does not involve the design and development of the active b.....
