The colours generated are stable over a wide viewing angle in both horizontal and vertical parallax.
Arkansas.gov: The new Arkansas.gov state portal website features a modern design and innovative features including texting service Gov2Go, Smart Search, vertical parallax scrolling and a mobile-optimized "responsive" design that ensures citizens can access the site on any device.
• Geometry Corrector—Automatically corrects vertical parallax and tilt of your S3D footage
Whereas an occlusal film together with a panoramic view are routinely used for vertical parallax. If the supernumerary moves in the same direction as the tube shift, it lies in a palatal position, but if it moves in the opposite direction then it lies buccally.
The quality of the obtained results is estimated by vertical parallax residuals in the measured points and root mean square (RMS) geometric models.
What errors of vertical parallax residuals and RMS will be used for measuring manual or stereo modes in overlapping images?
But as only a thin horizontal strip of the first hologram is captured, the image has horizontal parallax but no vertical parallax. As Benton points out, this is usually not significant for human viewing as our eyes are normally held horizontally and rarely do we use vertical parallax.
The holographic images are multi-channel, stereographic images capable of full vertical parallax. The incorporation of image data into the mastering system is possible from computer generated files, photographic input or 3D models.
The logo appears with both horizontal and vertical parallax, as opposed to rainbow holograms or stereograms where the parallax is constrained to one axis.
True, we needed to lose vertical parallax and replace it with a rainbow (pace Steve Benton) but for most purposes, the sacrifice was worth it.
It is produced using a multiple laser system to achieve a full-colour 3D hologram which retains the colours with horizontal and vertical parallax. As a security feature HD3D offers multi-channel 3D images which switch in either vertical or horizontal viewing movement, covert graphic features and serialisation capabilities.
Integral imaging (II) is considered as one of the attractive three-dimensional (3D) technologies since it can provide both horizontal and vertical parallaxes and quasi-continuous viewing angles [1-4].
