Images,3-D

CT scan is like an X-ray, but it uses multiple images to build up a more detailed, three-dimensional (3-D) picture of your brain.

A computer puts all the slices together to render detailed, 3-D images of the heart or brain and surrounding arteries.

Using these parameters, the 3-D position of a point in the scene, which is identified and matched in two stereo images, can be determined.

Seeing the two images together creates a sense of depth that the brain perceives as 3-D, without the help of special eyeglass lenses.

It's possible that a lot of time spent looking at 3-D images might have an impact on the development of normal binocular vision, she said.

Three-D technology capitalizes on this effect, taking advantage of the brain's ability to fuse two images into one.

Until now dynamic, holographic 3-D images suitable for practical uses did not exist.

The company said looking at 3-D images for a long period of time could have an adverse effect on the eyesight development of young children.

The result is that moving images can be seen in 3-D by up to four people, even as they squabble about who should sit where on the sofa.

The website contains imagery collected by two NASA spacecraft that together create "stereo" 3-D images of the sun's coronal mass ejections.

They launched the snakes from the top of a 15-metre tower and used four video cameras to construct 3-D images of the animals' trajectories.

Due to the 3-D movement of the camera, different parts of the images exhibit different image motion.

One of its products, HoloVizio, displays 3-D images that "practically surround" users, says Peter Kovacs, the firm's software chief.

If you see feature films, you must wear special glasses to see the 3-D images - in this case, liquid- crystal.

Some of them result from the design of the 3-D display but others can occur if care is not taken when generating the images.

So attention is shifting to the next frontier in display technology: three-dimensional (3-D) images.

"You could have 3-D images that are clearer and much more resolved, " Daraio said.

The processing software (Windows only; Macs need not apply) will then meld the two images into one frame that can be printed.

The eye naturally sees in 3-D, so adding depth to the images on screen delivers a more immersive and realistic experience.

The experimental results indicate that the algorithm is effective, especially for registration of 3-D medical images.

in this paper , some research about extraction of 3 - d information of building from high - resolution urban aerial images is implemented.

Perhaps doctors would embrace it as a way to demonstrate the 3-D brain images to patients at their bedside, he reasoned.

That displacement is measured with a laser beam to create a series of 2-D images of the sample, which are combined to generate a 3-D image.

Camera calibration is a critical step in Computer Vision, through which 3-D information can be extracted from 2D images.

Ultra-fast, ultra-smooth style of the 3 D images and perfect multi-ball pellets Taiwan and swing the bats.

Beyond that, even more elaborate technologies are under development that use holograms to display 3-D images.

Confocal scanning microscopy is a new technique which can obtain the 3-D images of samples by using scanning and computer processing.

Many stumbling blocks remain, however, including the added costs of filming and broadcasting 3-D images.

Stereoscopic Artefacts: Some artefacts can be visible when viewing 3-D images on a 3-D display.

In the past, the TVs used color-filtered glasses, resulting in images with somewhat lower picture quality.

The application of holographic technology to display true 3 D images is a bright spot in the display field.

Canesta has spent 11 years building chips that process images and information about distances to give devices some 3-D oomph.

Hence stereo projections create 3-D images that appear to have a continuous presence both inside and outside the projection room.

The resulting image will look just like any 3-D picture, with two images slightly apart from each other.

Potential for use of HARP images in fast imaging techniques and three-dimensional (3-D) analyses are discussed.

It would help doctors a lot, for example, if the images from endoscopes could be shown in 3-D.

Experimental result show that it can reach a good subjective impression on aligned 3-D images.

But with poor color quality and unsteady images that induced nausea, 3-D didn't take off.

Update: To answer one reader's question: yes, the Lytro camera takes 3-D images.

Methods The color process were differently applied in all 420 3-D images of spiral CT.

An alternative approach to creating 3-D images is based on holography.

At last, we get the contour of all these images segmented and realize 3-D surface reconstruction, which is virtual endoscopy.

Methods 102 gravidas were scanned by 3 D probe in order to reconstruct 3 D images.
