what is 3d flat bed scanner?

Answer
it is simply a flatbed scanner that is able to scan in 3D, most scanners will only scan in 2D.

Why dont airports use dogs instead of those 3d body scanners?

BillsGold

Dogs could detect everything those scanners do and more. Why not make them standard at every airport gate? My own theory is that you cant make a lot of money from dogs so there's no lobbyists advocating for dogs. You can make money off of those scanners ($150,000 a machine?). Is our security being subverted by washington lobbyists?

Answer
If each team had several dogs all trained in detecting different substances, the handlers could simply walk the dogs along the line of waiting passengers and remove anyone the dogs "hit" on. Forget technology, let nature expose them. I agree. Dogs not scanners.

Java programming help, 3D room?

ali

Okay, I'm beyond lost at the moment. As you can tell, I'm a sucky programmer and I have a project due and any help on this would be awesome. Even just to get me started and get my brain cells moving hahaha

Okay, So. I have to write a program that separately prompts and inputs the length, width, and height of a room. Then, taking the floor of the room, it will calculate the rooms area and perimeter. THENNN, taking the room as a rectangular solid it will calculate the rooms surface area and volume. Then output the labeled results.

Answer
You'd get input like this:

======
Scanner inScanner = new Scanner( System.in );

System.out.print("Enter room length: ");
double length = inScanner.nextDouble();
======

You only have to make the scanner once, and can use it for all three inputs. I don't know if you are allowed to assume integer inputs (inches or rounded-off feet?).

Once you have length, width, and height, the rest are pretty straightforward, aren't they?

floor area = length * width
perimeter = 2*length + 2*width
volume = length * width * height
surface area = 2*length*width + 2*width*height + 2*length*height

Output is pretty simple:

System.out.println("Floor area = " + (length*width) );
(and analogously for the others).

Is there some other specific issue you are having?

there are 3D printers, that prints plastic printers. are there 3D scanners?

Jim

i understand that there are "scanners" that tells you how much of a certain element there are in a sample.

relating to this question, are there printers that also print other material?

Answer
Do YOU have any idea what you are talking about?

There are "printers" that can "printer" a 3D model using a special plastic polymer.

There are also "scanners" that can scan the dimensions of a 3D object. Most often, the input from the scanner can be used to make a plastic model of the subject using the 3D "printer".

BOTH are very expensive --several thousand dollars.

Other than that -- set back, take a breath, ask a clear and understandable question.

What is the legality of 3d scanning?

3d scanner uses image

masterofwi

What can i do and not do using a 3d scanner.
I assume if i wanted to I could scan someones batman figurine, but could i make a "batman movie" out of it?
Could i make a knockoff using their figureine scanned model?
Is there any reason using the scan of anything comerically is illegal in the united states?
I'm just worried because a 3d scanner would be pretty useless if you couldn't use the scans of anything commercially.

Answer
3d scanners are not used to copy or rip off designs from others
you make ur own character figureine and scan them and use them commercially

What is the coolest gadget that you own?

Q. I own a bar-code scanner :)

It may probably be dumb and corny to you but is great for me...you see, I use the line laser as a 3D scanner to build geometry graphics.

COOL!!! ain't it?

Answer
an electric tin opener...

How far is the automated 3-D segmentation of Brain MRI efficient compared to manual segmentation?

Sandhya

We are doing a project on automated 3-D segmentation of brain MRI using MATLAB. We would like to know the extent to which "Surf" commands are efficient in producing reliable segmented 3-D image. The accuracy level, how much it is better compared to manual segmentation. We need statistical detail, kindly help us....

Answer
This correspondence deals with the development of an
automated 3-D segmentation of Brain MRI. The proposal is a
model-based approach for accurate, robust, and automated
tissue segmentation of brain MRI data of single as well as
multiple magnetic resonance sequences. The main contribution
of this study is that we employ an edge-based geodesic active
contour for the segmentation task by integrating both image
edge geometry and voxel statistical homogeneity into a novel
hybrid geometricâstatistical feature to regularize contour
convergence and extract complex anatomical structures. We
validate the accuracy of the segmentation results on simulated
brain MRI scans of both single T1-weighted and multiple T1/
T2/PD-weighted sequences. When compared to a current stateof-
the-art region based level-set segmentation formulation,
our white matter and gray matter segmentation resulted in
significantly higher accuracy levels with a mean improvement
in Dice similarity indexes. Thus the development of the project
is done using MATLAB simulation for results.
A Hybrid Automated 3D Segmentation in Brain MRI -------------------------------------------------------- Advantages of a MRI scan
⢠MRI scanners are good at looking at the non-bony parts
or "soft tissues" of the body. In particular, the brain, spinal
cord and nerves are seen much more clearly with MRI
than with regular x-rays and CAT scans.
⢠Also, muscles, ligaments and tendons are seen quite well
so that MRI scans are commonly used to look at knees
and shoulders following injuries.
⢠A MRI scanner uses no x-rays or other radiation.
⢠A disadvantage of MRI is itâs higher cost compared to a
regular x-ray or CAT scan. Also, CAT scans are frequently
better at looking at the bones that MRI.

Why can’t biometric identification be used to make purchases online?

3d scanner uses image

Emma

Biometric identification is basically face recognition, eye scanner or fingerprints which could be used instead of passwords and user names etc
I don't know if the answer is that you can't buy the technology yet to actually do that from home or because your fingerprint etc hasn't been linked up to your bank details or whether it's something blatantly obvious that i have missed.
Thank you for your help

Answer
I have recently gone across this great time and attendance device called SmartXS which scans on multiple levels and is really fast. They provide software support through which it can be customized and used for various applications. Even several banks have been using fingerprint scanners for the identification instead of writing PIN codes in their ATM machines. Face recognition will definitely take it to another level as this device scans dual retina and 3d face in less than a second. The company is Solotech Corp and its design is good too. Hope it helps.
