How can you detect irregular edges using the IMAQ add on?

Im currently trying to use the IMAQ add-on for LabView to detect the edges of an irregular image. I have attached the image I am trying to detect the edges of. I have tried using everything in the "locate edges" sub-pannel (i.e.. imaq find edge, imaq find circular edge etc.) but none of them have yielded any favorable results. I think the "IMAQ edge tool 3 IV" might be what im trying to find however I don't understand how to get any usable data out of it.
Thank you, all comments and help are greatly appreciated.

Hi Dander,
I am not sure exactly what types of edges you are trying to acquire, but I used one of the examples from our Example Finder and was able to detect edges on your image. I will say that with the image that you are using, the edges are not very well defined, so you may not get a 100% accurate measurement. The example that I was using uses the IMAQ Edge Tool 3 VI and the example can be found by going in LabVIEW to Help>>Find Examples... From there, you will go to Toolkits and Modules>>Vision>>Functions>>Edge Detection Example.vi. After that, you will remove the build path function and input a path to the image. I hope this helps!

HT201303 How can you tell which devices used the Apple ID? For example: "twoPads, 2 iPhones and 1 computer used your Apple ID ?"

I believe my kid gave somebody my password to download something. And I want to know who? Can it say For example: "2 iPads, 2 iPhones and 1 computer used your Apple ID ?"

Only if they went to the trouble of setting their device up as a "Managed Device" on your ID.
Change your password.

We are evaluating the use of iPod touch devices to record best practice videos on our manufacturing floor and to post to an internal Moodle web site. How can you upload a video from the iPod touch to a site other than YouTube?

We are evaluating the use of iPod touch devices to record best practice videos on our manufacturing floor and to post to an internal Moodle web site. How can you upload a video from the iPod touch to a site other than YouTube? The Moodle upload interface is expecting a file selection dialog box like windows or OSX. I do not want to have to go through an intermediary step of messing with a pc.
Thanks!

It should be around 7 and a half gigs. In iTunes, across the bottom there should be a bar that show how much storage is being used and by what. (music, movies, apps, etc.) To make music take up less room, you can check the box to make it convert the music to 128kbps AAC. This lowers the quality, but with most earbuds and speakers, you can't even tell the difference.
The iPod touch has parental controls built in. You'll find them in Settings. I think they only work for enabling/disabling Safari, Mail, YouTube, and App Store. Here's an app that does more: http://www.mobicip.com/online_safety/ipod_touch

Hello! I'm out of the country and all my iWeb information is on my computer at home. Now I need to make changes on the webpage... how can i do that without using the computer i made the page on? Thank you!!

iWeb uses the domain.sites2 files to store its assets.
You'll find it here :
~/Library/Application Support/iWeb/
where ~ is your Home directory.
If you take a computer with you, you have to store that file in the same location.
It's not different from taking documents with you if you want to edit them.
A solution is to remotely control your computer at home.
TeamViewer, LogMeIn, Apple Remote Desktop or any VNC application you can use, like "Chicken of the VNC".

I have two Apple ID, how can I delete one and use the email address associates to the main one?

I have two Apple ID, how can I delete one and use the email address associates to the main one?

If you abandon one of the Apple IDs you will also basically be abandoning any content that you have acquired with that Apple ID. Content can only be updated and re-downloaded with the Apple ID that was used to buy it. Apple will not combine the content of Apple IDs and Apple will not transfer the content from one Apple ID to another Apple ID.

Developing a 2 page form, username on the 1st page, password on 2nd how can i force FF to use the username from previous page when it asks to remember acct info?

I am developing a 2 page signup form, where the person enters their username on the 1st page and password on the 2nd.
When I test the form, FF asks to remember my password for the site - however it thinks the zipcode (field above the password) is the username on the account.
I have tried to put their username/email in a hidden field on the 2nd page, just above the password field - and that did not work.
How can i force FF to use the username from previous page when it asks to remember acct info?

This website is using autocomplete=off to prevent Firefox from saving and filling the name and password.
You can remove autocomplete=off with a bookmarklet to make Firefox save names and passwords and other form data.

Please Help. How can you monitor a directory using jndi connection to a ldap server?

How can you monitor a directory using jndi connection to a ldap server? I
want the ldap server to monitor the content change in a file system
directory on another computer on the network. Can someone please help.
Thanks
Fred

Hi,
Why do you want to use LDAP for Hard disk monitoring..???
U can do this by creating a MD5 checksum for all the files existing in some
perticular
directory and every hour or any configurable period u can recalculate the
checksum
to find out the change in the content.
I guess all u need is to get the code for "updatedb" utility of Linux and
instrument it for ur needs..
Hope it helps...

You could use shared variables and publish them to the network or use data sockets.

In print preview - how can you have multipage previews of the document - 1 - 2 - 3- 6 - 12 page preview and so on so that you can see if the document is ok to print?

WINXP - In Explorer you can have multi-page print previews from 1, 2, 3, 6 upwards to check and confirm that the document will print correctly to your needs - and does this across the screen format as opposed to down the page, so that you can see all 12 pages on your screen to quickly see that the print percentage is correct and all pages fall into the print area and so on - how can you set this up with Firefox, because printing with Firefox is so unstable, you don't know what to expect when printing a document or web page?

No what I mean is how can you see many pages across the screen without having to scroll like in explorer where you can see 12 or more small pages on your screen without scrolling down, like tiled across your screen as opposed to vertical down the page. Thanks

How can you download premier pro when the icon doesn't exist in cloud?[was:pr]

how can you download premier pro when the iucon doesent exist in cloud???

In order to download the software, your computer must meet the system requirements to run the software.
http://helpx.adobe.com/x-productkb/policy-pricing/system-requirements-premiere-pro.htmlhttp://www.adobe.com/products/premiere/tech-specs.html
The usual reason for not being able to download is that Premiere Pro (and other video apps such as After Effects) are 64 bit only so they require a 64 bit computer and a 64 bit operating system.
If you're running a 32 bit computer and operating system then you will not see the Premiere Pro icon since the software will not run on your computer.

How can you minimize or (turn) off the "side panel" in Web Intelligence in the view mode.

How can you minimize or (turn) off the "side panel" in Web Intelligence in the view mode.
It is possible to turn on/off options within the Side Panel by Customization of Groups.
But it seems You cannot influence the way Web Intelligence present (minimized or Off) the Side Panel in the IE??
Is there a solution for this??
If not, it would be a nice property of a Web Intelligence document in a future release.

Hi Nico,
we patched up to BI 4.1 SP 3 Patch 2

How do I increase the maximum number of images I can acquire in a sequence using the IMAQ 1424 with 80 MB of onboard memory and a Duncan Tech camera?

I've increased the maximum number of buffers to higher than I need, but I still cannot acquire more than 139 images with the Duncan Tech digital video camera before I get a memory lock error. Is there any way to increase the number of images I can acquire in a sequence using the IMAQ 1424 with 80MB of onboard memory?

It sounds like you are already bypassing the onboard memory. If you weren't, you would only be able to acquire about 20 images.
If I understand correctly, you do not convert the images until after you acquire them. This means each acquired image is 4.13 MB, and 139 images will take 574 MB of memory. I wouldn't be surprised if that was all the free memory available on a 1 GB machine. The operating system, LabVIEW and any other software running probably take up the rest of the memory. You might want to put your computer on a diet and minimize the number of other programs and utilities running. The only other option I see is getting more memory if possible.
Is there a way that you can reduce the number of images you need to acquire? Pe
rhaps skipping every other frame? Do you really need more than 139 images?
Is it possible to acquire the images in monochrome? That would triple the number of images that you could acquire.
