Third Report on Stereoscopic Film Quality Released
Researcher Denis Sumin and his supervisor Pr. Dmitriy Vatolin from Lomonosov Moscow State University in Russia are leading a project on 3D stereoscopic movie quality assessment called VQMT3D (Video Quality Measurement Tool 3D).
The Lab decided to analyze several stereoscopic films and to investigate the potential reasons of headache and eyestrain often suffered by some moviegoers. The first two reports were focused on films captured with stereoscopic camera systems, and the main problems discovered during the film analysis were: excessive horizontal disparity, vertical disparity, color mismatch, and sharpness mismatch.
Report #3 of 6 has just been released in August 2013 (free access to all 3D professionals -see links here under). Report #3 analyses in great details -literally image by image and pixel by pixel- specific 2D-to-3D conversion metrics such as edge sharpness mismatch and cardboard effect for the following movies: Alice in Wonderland, Clash of the Titans, Conan the Barbarian, Green Lantern, and Abraham Lincoln: Vampire Hunter.
3D Shooting Through a Single Lens
Professor Kenneth Crozier and graduate student Anthony Orth, both at the Harvard School of Engineering and Applied Sciences (Cambridge, MA, USA) have developed a way for photographers and microscopists to create a stereoscopic 3D image through a single lens, without moving the camera.
This improbable-sounding technology relies only taking two pictures with different focus and handling them to a sophisticated algorithm. The method requires a reasonably large lens (i.e. a DSLR camera, not a smartphone one). Details and a short but impressive video demo here under.
Watch 3D (with Glasses) and 2D (without glasses) at the Same Time
Researchers at the University of California Santa Cruz have developed a 3D display which can also be viewed in 2D without glasses, and without the blurred effect caused by overlapping images. Though, as you'd expect, the screen displays both left and right images, it also emits a mysterious third image which is the key to the technology.
How It Works
The projector displays alternatively three images every 1/120th of a second: left eye, right eye, and inverted right eye. Seen without any glasses, only the left image is perceived as the inverted right image cancels the "normal" right one.
With the active stereoscopic 3D glasses however, only the left and right images are passing through and reach the eyes, allowing the viewer to perceive a normal stereoscopic image.
No-glasses 3D Tangible Interface Demonstrated
Researchers Takumi Kusano, Takehiro Niikura, and Takashi Komuro from the Komuro Laboratory (Saitama University, Japan) propose a virtually tangible 3D interaction system that enables direct interaction with 3D virtual objects which are presented on an autostereoscopic (glasses-free stereoscopic) display. Watch the demo here under.
Nasa TWINS Stereoscopic Spectrometers
Surrounding Earth is a dynamic region called the magnetosphere. Five years ago, on June 15, 2008, a new set of instruments began stereoscopic imaging of this mysterious region. Called Two Wide-angle Imaging Neutral-atom Spectrometers or TWINS, these satellites orbit in widely separated planes to provide the first and only stereo view of the ring current. TWINS maps the energetic neutral atoms that shoot away from the ring current when created by ion collisions.
In five years of operation, the TWINS maps have provided three-dimensional images and global characterization of this region. The observatories track how the magnetosphere responds to space weather storms, characterize global information such as temperature and shape of various structures within the magnetosphere, and improve models of the magnetosphere that can be used to simulate a vast array of events.
