I am having trouble using the IMAQ command RejectBord​er. Can somebody give me some guidance?

My image is 768x576, which I confirmed by right-clicking on the Image Info property. I set a border using the Image.Border = 20.
When I threshold, then do a RejectBorder, blobs along the top and left sides of the image are eliminated, but not those along the right or bottom.
Any ideas?

Try setting the property image.BorderWidth to be different values and see if this changes the blobs that are eliminated. The border should be even all the way around the image.
Take a look at the example program called Blob Analysis in the folder C:\Program Files\National Instruments\VB\Samples\IMAQ\2. Functions\Binary Analysis for an example of using this function.
Hope this helps -

    Is this a new Apple iD? If it is, and you have already set it up, then you have two options:
    1.     Temporarily put a Credit Card or Gift Card on the account to download the free app. If you put a credit card, then once you have downloaded the app, you should be able to go into your Account preferences and change the payment option to = None.
    2.     You can download the fee App, and then set up a new Apple ID.

  • LR V1.2 Having problems using the find Command

    Have just recently started using lightroom and so far managing most applications imported a series of photos and after import added keywords to them using the find function I cannot get images to appear. What seems to happen is that in the keyword tag and the folders any of the headings that contain the keyword become active the remainder show a zero no in number of images held in that folder but no images on screen
    can anyone assist me
    Peter

    thanks for the reply
    have switched of global filters, made sure that using the Find command have set keywords in "text box" and in the "rule box "contains". When I then enter a key word as soon as a type the first two or three letters
    a message appears on the screen no "No photos in the selected keyword Tag" Also when you look at the folders which have a series of numbers indicating the photos in the directory the first number in each set turns to 0 with the exception of the folder and sub folder were the images are
    So have not managed to make any progress

  • I just had my logic board replaced. now im having trouble using the interent even with a strong connection and the internet is working on other devices!! please help me :(

    I just had my logic board replaced. i am now having trouble with using the interent even with a strong connection. all other devices are having no problem with the internet. please help

    Test while started in Recovery : if the problem persists, then it likely is a hardware issue.
    Resetting the System Management Controller (SMC) probably won't change anything, but you can readily do it before contacting the repairers.

  • Having trouble using the replace() function

    Hey everybody. :)
    I've written a query which finds the address for a company (from 5 columns and concatenates them into one). These columns are street, town, county, telno and faxno.
    Some of the companies have a null value for the county, so when I write the query it returns a result like... 3 Main Street, Manchester, , 0384758948, 04857846927, but if there was a county it would be 3 Main Street, Manchester, Greater Manchester, 0384758948, 04857846927.
    I've been trying to write the query so if there isn't a county, it just removes the comma and the address becomes 3 Main Street, Manchester, 0384758948, 04857846927... but I just can't seem to figure it out so I thought I would come and ask the professionals. :)
    set linesize 100
    column suppname heading 'Supplier Name'
    select suppname, street || ', ' || town || ', ' || county || ', ' || postcode || ', ' || telno || ', ' || faxno "Supplier Address"
    from Suppliers
    where county is null
    replace(county, county, '');
    This gives me a 'command not ended properly' error, but I can't for the life of me figure out why.
    Thank you in advance. :)

    select '3 Main Street' street,

  • I am having trouble using the clone tool and eraser tool.

    I am not able to see my brush get bigger as I increase the size.  Once I clone an area, it selects what I want to clone, but it won't paste it on the photo.  I cannot also use my eraser tool.  It does not show the line that usually is shown in white before it erases the area. I am working on a background copy. 

    Suggest that you reset all tools to default.
    Look for this box icon with lines in it on a tool's option bar. This is for PSE v. 12 and perhaps for v.11 (I'm not certain about 11)
    For earlier versions of PSE, look for a little arrow, top left, on the option bar

  • I'm having trouble using the Ipod Updater

    Itunes is not recognizing my ipod. I was told by the apple support to download the Ipod Updater and restore my factory settings. I downloaded the Ipod Updater as instructed, but when I go to open the program is keeps saying "Error reading setup initializing file".
    I'm all ears...

    "Make sure your folder names don't contain strange characters
    If the iTunes installer (iTunesSetup) is not responding or appears frozen after launching the installer or the iPod installer (iPodSetup) reports "Error reading setup initialization file" then the folder(s) where the installer is stored may contain unusual characters. This often results from copying a folder to your Windows system from a disk or network that is not natively formatted for Windows. If you notice that the iTunes or iPod installer or stored in a folder like this, either rename the folder or move the iPod or iTunes installer to another location before launching."

  • Is anyone having trouble with the singing santa app?

    Anyone having trouble using the Singing Santa app. It worked for me last Christmas. Can't get it to process video this Christmas. I've deleted the app and downloaded it again, but I am having the same problem.

    Have you tried turning your iPod off, then back on? Or a reset, press and hold both the power and home buttons together until the Apple logo appears, about 15 seconds+/-, then release both buttons. If still no joy, try going into Settings>General>Reset tap tap Reset All Settings. If problem continues connect to your computer, make backups of the stuff on your iPod to your computer, then Restore from backup, if still not working Restore to New. then reinstall your stuff. If restore to new does not correct you may have a hardware issue, contact your Apple store or Apple Genius Bar, make an appointment and have your iPod evaluated. Good luck, Cheers.

  • IIs there any way of loading in a MM54C221J component into multisim with out having to use the component wizard?

    Im trying to use a MM54C221J multivibrator in multisim, but it's not in the library.
    Does anyone know if I can get hold of one with having to use the component wizard?
    Many thanks 

    Hello GFear,
    There are several sources for components that aren't native to multisim.
    You can directly contact the manufacturer of the component should they have the multisim model available.
    You can also search the web incase another user has created the component.
    I have searched for the MM54C221J and have not found one available online.
    If you are having trouble using the Component Wizard here is a useful link that breaks down each of the steps.
    To create a component you will need a spice model of the component which you should be able to acquire from the manufacture.

  • Having trouble with the HTTP Server vi

    I'm having trouble using the HTTP Server program to view the front panel of my program remotely.
    When I initially start the server program everything works fine. However, the program hasn't been able to run for more than one or two days at a time before it freezes and won't display the front panel.
    The only clue I can see as to what is going on is that there are always several pending connections and active connections listed in the HTTP Server front panel when it isn't working properly. Stopping the server and starting it again fixes the problem temporarily and it works fine for another day or two.
    Any ideas about what might be causing this problem?

    Which OS do you have? Win95 and 98 are not very stable systems, so you might want to try with WinNT. You should be able to run the HTTP server for few days on WinNT.
    Since restarting the server solves the problem, maybe you can try to programmatically restart the server every 24 hours. This can be done within LabVIEW with the HTTP Server Control.vi. Be aware that this will close all the connections, not just the pending ones.
    Does this problem happen every couple of days, or are you able to run it sometimes for a longer period time? Is it related to how many clients request control?
    Also, take a look at the Access Log, and see if you notice anything strange at the time when the problem happens.
    I hope this helps.
    Have a pleasant day.

  • Trouble using the Web-based utility

    I have a WRT54G wireless router, V8, firmware 8.0.0. It is Ethernet-connected to a Windows Vista machine running SP1.
    I am having trouble using the Web-based utility. I can access it but cannot make any changes.  For instance, if I change the settings on the Setup page and click "save", I get a "This webpage is not available"
    I tried updating the firmware and got the same message. Disabling my personal firewall has no effect. Resetting the router from the button on its rear panel has no effect. I tried using with both Windows IE and Google Chrome browsers and got the same result.
    I have been using this router without problem for months using a a Windows XP machine. This problem may be associated with my changing it to the current Windows Vista machine. I no longer have the Windows XP machine.
    Please help me. Thank you and Happy New Year!

    I spent a full day unsuccessfully trying to make it work, including numerous Linksys utilities downloaded from the site. I could not conjure any support on Linksys chat, and the live body on the Linksys tech support line wanted to charge me $29 for his help.
    I finally succeeded by purchasing and installing a Netgear wireless router ($44, Staples) that came up flawlessly the first time. The Linksys device is in my trash. 

  • I need to un-install then re-install my Adobe Creative Suite 6. I am having troubles with the programs.

    I need to un-install then re-install my Adobe Creative Suite 6. I am having troubles with the programs.

    Hi legates1,
    You can uninstall the software by going to Control Panel > Programs
    You can also use the Creative Suite Cleaner tool ( Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6 ) to remove the software completely.
