I,ve been trying to use the "IMAQ Count Objects" but it seems it does not return anything. I,m not sure if i need a grayscale image as an input? anyone can help

Any more information on :IMAQ Count Objects" vi?

It looks like you are correct. I was thinking of the input to "Complex Measure", which requires the binary image. I started with IMAQ back when we had to chain all the routines together ourselves, instead of having a single vi that did everything for us.

    The Ask Toolbar is causing that in the Firefox 3.6.13+ versions. Uninstall that extension.
    There are a couple of places to check for the Ask toolbar:
    * Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
    * Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

    I have tried restoring an Ipod Nano 6th Generation but it seems to keep looping back and saying it is in recovery and needs restoring, can anyone help?

    Try doing a level reformat of the iPod's flash storage instead to see if that kills the restore loop using the instructions in the article below.

    Apple id : [email protected]

    If the old ID is yours, and if your current ID was created by editing the details of this old ID (rather than being an entirely new ID), go to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID.  Click edit next to the primary email account, change it back to your old email address and save the change.  Then edit the name of the account to change it back to your old email address.  You can now use your current password to turn off Find My iDevice, even though it prompts you for the password for your old account ID. Then save any photo stream photos that you wish to keep to your camera roll.  When finished go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud).  Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was.  Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

    My itunes library is much bigger than the 64gb on my ipod touch, but I want to update the touch to ios5.1. I tried the ipod backuo funnction, but this only produced a small file, much smaller than 64gb. If I upgrade, will i lose all the music and books as currently constituted on the ipod touch?

    The iPod backup that iTunes makes does not include synced media like apps and music.. See the following for what it contains.
    iTunes: About iOS backups

    iTunes Store: Transferring purchases from your iOS device or iPod to a computer
    - Transfer other music by using a third-party program like one of those discussed here:

  • I am trying to use the Home Sharing feature but none of my current library is showing up under my Share Library ?

    I recently purchased a new lap top and thought the easiest way to move my library before wiping my old lap top would be the Home Sharing feature.   I have gotten everthing set up for Home Sharing but the library on my current laptop isn't showing under the shared library?  I am using the same account log in that I have always used and the Home Shared library isn't even seeing purchases under my account?  How do I get the Home Shared library to see all my music?

    What operating systems are you running?

  • HT201209 My daughter tried to use the following gift card that she had received and received a message about it not being properly activated.

    My daughter tried using an iTunes gift card that she received and it indicated that it was not properly activated. 
    <Edited by Host>

    Do not post card codes or any other personal information in these forums. These are open, public forums, not a way to communicate with Apple, so posting any such information here just gives it to the entire world. I'll ask the Hosts to remove the code and you'll just have to hope that no one is able to redeem the code before you can.
    As to the problem, what you normally should do when you have an iTunes card that has not been activated is go back the retailer from whom you purchased the card and discuss the problem with them. They should either correctly activate the card or give you a new one. If they refuse to help, as some retailers do, or you don't know or can't get to the retailer, go here:
    iTunes Support
    and follow the instructions to report the issue to the iTunes Store. They will ask for a scan of the front and back sides of the card as well as a scan of the receipt
    Regards.

  • 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!

  • School issued laptop, pop-ups, permission to use an applicaiton to stop showing up, even when I have not tried to use the application

    I have a school issued laptop that is having a problem that has completely destroyed the useage. Every couple seconds a message will pop up that says "you do not have permission to use the application "spotifywebhelper", "Usutil", and "Student". The problem is that they do not stop. No matter how many times you click the okay button they come back in a couple seconds. I have tried to run a self service fix that is supposed to fix problems on the computer functioning, but it has done nothing. I sent my tech administrator a message but I have not gotten a response yet. This is a school issed laptop, so I cannot get into the things I think I need to stop this problem. If anyone can help me, PLEASE DO. I need my laptop and it has been rendered useless by these irritating and frustrating pop-ups that have caused this message to take about 10 minutes to type...

    Boot in the usual way and enter your password at the login screen. Then hold down the shift key and click Log In. If you can do that, your login items won't be loaded. If you're going to tell me you log in automatically, then I don't have any other suggestions. It's a problem for the school's IT department.

  • I upgraded to 20gb iCloud but it isn't enough to back up. I get constant error messages saying there is no backup space and I've not been able to use the upgrade. Apple promised to refund then didn't. Please help is there anyway I can use this space?

    If you were told they would refund the price for the iCloud storage - Contact AppleCare and ask to speak with a senior advisor.  Have the case number for the promised refund available.
    If you are trying to update your device, but you don't have sufficient space to download and install the update, you need to delete content from your device.  Buying storage in iCloud does not add space to the device which is what you need.
    You can always update using a computer with iTunes installed - this method is faster, and will allow you to make a backup on the local computer (Local backups restore faster than iCloud backups).
