The best methods to prepare to read a display 7-segment

What are the best techniques to use to get the imaqFindLCDSegments works well?

I'm currently thresholding of image and using erosion Morpholgy tool to separate the segments but am gettign an error saying that "the input image is not an LCD or LED valid calibration image.

Using this function with imaqReadLCD I can read numbers, but all the letters appear to be a problem. C all error above a L manages to move the stadium to find the causes, but at the stage of the reading, I said that the KING is not valid

Thanks in advanced for any help


Thanks for all your help.

I found that the threshold is set too low because I spent a binary level with high contrast. Which has much improved the performance of the service.

I now use segments to identify the characters, because it is a feature that I had forgotten!

Thanks again!

  • Please wait while the document is being prepared for reading

    I just upgraded to Acrobat Pro DC. I now get the following on some of my documents error message: "Please wait while the document is being prepared for reading". For a large document, it takes a desperately long time to read all the pages. And the message appears whenever I open it.

    I tried to get help from a support technique cat last night. I was told that I could go back to the latest version of Acrobat Pro. It is a sad reflection on the company.

    I really don't like something on the DC, but I know that most of the problems will be fixed within the time with updates.

    Thanks for any help,

  • When I plug my portable hard drive to the usb port it does not read and display the contents...

    When I plug my portable hard drive to the usb port it does not read and display the contents...

    Hi deaza,.

    Ø Have you connected the USB hard drive to the computer directly or you have used an external USB hub to connect?

    O trying to connect to another USB port to check if it works?

    O the hardrive shows in windows of the computer when you connect it?

    Method 1:
    If you have installed security software, I suggest you to temporarily disable the security software and connect the USB and check to see if the same problem happens. Make sure that you enable the security software after checking.

    Alternatively, you can try to plug the USB key into a different USB port and check if it helps.

    Method 2:
    I suggest trying to launch hardware and troubleshooting of devices and check to see if it helps, here is the link: ' t-installed-correctly

    Method 3:
    If this does not help, then follow these steps:

    (a) remove all your USB devices. Use the safely remove the feature to turn them off.

    (b) open Device Manager and navigate to the section for USB. Uninstall all USB drives. There should be one for each USB port, and then restart.

    To open Device Manager, go to the link below and follow the steps:

    (c) Windows should re - find all of the devices. If it is not the case, note the error message and let us know.

    You can also navigate to the link below and follow the steps to install the USB device.

    I hope this helps. Let us know the results.

  • Different screen resolutions - what is the best method?


    I know that this question was asked a thousand times before, but what is the best way and the most reliable to deal with different screen resolutions?

    I read a lot of posts about it and tested on everything: unique, methods, combinations, let labview scale my objects, their scale by myself, etc. Another alternative that I found was to design the front panel to the lower screen resolution, let labview scale objects (graphics, controls tab and decorations) as window increases or decreases and lock "groups of indicators, controls and text" to prevent them from scaling and overlap. However, if I lock these "groups" that they don't move in the right place in the resizing of the window. Then, I put these 'groups' within groups and tried to compensate for the position via the property node, but it was not possible because the 'groups' within the cluster have been locked!

    After all these tests, I realized that the best way to manage different screen resolutions must have a main VI that detects the current screen resolution and load the good VI for this resolution. The problem is that I have a VI for each screen resolution (created one by one) and if I want to move the code I have to do the same task for all the screws

    Since I already have all the screws (for different screen resolutions), I could get the sizes and positions of all the objects through property nodes and create a kind of 'cluster' which, after the detection of the current screen resolution, would be to adjust all the objects. But I have several decorations in the front panel and I can not get information via the node property of them.

    THW way you can prevent the control to move when you're scaling, is to group the controls with 'something' which is placed outside the façade. In the example I give you now, you can see that I have grouped the stop button and the 'red faces' with a 'point' on the left side of the front panel.

  • What is the best method to move from an iPhoto from one Mac to another library?

    What is the I best method for export/transfer my iPhoto on MBP to the iPhoto library library on my iMac? I prefer to keep my metadata intact; I guess that to do a package contents 'show' of my iPhoto and AirDropping the 'masters' library, I won't lose it? I'm under El Capitan 10.11.4 on Mac.

    I just want to explain my situation because maybe I'm missing something. I have SUMMER will use the photo library iCloud for synchronization on all my Apple devices and as a backup off-site. Fortunately, I realized soon as enough it would become a management NIGHTMARE. I downloaded everything from iCloud to my MBP and want to get it all on my iMac, so I can clean up the mess of duplicates and others.

    I couldn't synchronize with realism of the iCloud photo library to my iMac because I would have had to download about 150 + GB of data, so that I can download the 30 or GBs who were on my families iOS devices iCloud and the MBP. ICloud photo library interface is NOT well designed or easy to use - download directly from the cloud is heavy at best.

    All tips are appreciated, thanks.

    Simply connect the two Macs together and drag the library in the pictures of the new mac folder - or use an external hard drive to the Mac OS extended (journaled) format and drag through - then launch iPhoto on the new system

    Move the masters moves original photos and metadata exactly as they were imported without organization

    And iCloud library isn't an option for iPhoto - it requires OS X 10.10.1 and photos 1 or later version

  • Is anyone know the best method to remove background on Photoshop CS4


    Background is too dark, want to brighten up.

    Use for the site to the beauty of the skin

    You cannot use this image on a commercial Web site!   Go back and resume.  What is the light source?

    There is something we used to do with Photomatix (HDR software) where take you a bunch of shots fired a strobe at a different location for each shot and use the best of each shot in the merger.  I have a feeling that if you did it with Photoshop. Load the shots in layers. Used Edit > Auto alignment of layers, followed by Edit > layers of automatic mixture using seamless tones and colors, it would do the same.  I could just go and check it out.

  • What is the best method to put a form in a DPS iPad app?


    I need to create an iPad App using adobe DPS which includes a form. This form data should be collected in a database.

    What is the best way to achieve this? I know a html but I'm not a coder, I'm looking at options can I perform I hope relatively simply.

    Any suggestions?

    Thank you very much

    Yes, HTML forms work best. There are tons of sites that also offer pre pready HTML code (e.g. Add a WebForm to an Adobe Digital Publishing Suite Folio ) and the direct URL that you can use as Web Contect to display the form as or etc.

  • What is the best method to refresh the content of the screen (possibly push refresh)?

    We use Coldfusion 9.0, and our question is simple.  We were asked to do some screens display to set up a schedule of events.  So, we created a Publisher backend HTML fast and made the client refresh every 30 seconds with meta refresh that displays the screen that is published.  Wonderful œuvres.  A change is made, the screens to be quickly updated in 30 seconds or less.

    This weekend we had an update put the server to this plate up a larger problem.  Update temporarily stop the Web server and which caused the display to the standard site is not reachable (diagnose connection, etc.).  At this time where the discount is killed, display screens are dead in the water until someone knocks f - 5.  Makes us think that whenever we have any operation of blip, the screens will have to be touched.  It is a small project, we wanted something simple and we got it.  I'm afraid that now we just created a situation of surveillance techsupport involuntarily.

    Which brings me to the real issue.  What is the best practice to do?  After doing a google search, it seems to be all sorts of directions to go.  I don't want a complex solution because the decision not to outsource was based on the speed of a project, it was.  I'm hoping to get some tips on how to make a simple pressure of the HTML to a screen in a Coldfusion environment.

    Thanks in advance for any help offered.

    Thank you very much for your answers.  I think we're going to depend on the network is stable and organize updates on the server at the time we can monitor screens.  After researching the issue, we found that it is a little more deeper than at first glance.  We found which is a good lead if we go to another direction, or someone else has a similar problem: _ (programming)

  • Help for the best method of production meadow with Canon XF305


    I'll make some animations based on Canon XF305 images and HDR images.

    The output will be used in a web page and displayed on a large format JWPlayer with a streaming service.

    I film with the 720 p 50 MB/s rate because I want to take advantage of the 4:2:2 color sampling (a lot of seizure will be used!). My question is: what would be the best order of production to get the best

    output at the end.

    * Is it better to convert the raw images in Premiere - Pro before its importation in Aftereffects, or is it better to keep it in the original format?

    I have a computer with 6 core 3.4 Xenon, 24 Gig memory, GTX580 and two drives Raid 0 Rapids chained together.

    CS 5.5 Adobe Production Suite.

    The compositions are no more then 6 layers at the same time and will be merged later.

    Thanks David

    Have you looked at this document? It is the first result when searching 'canon xf305 first pro workflow' with Google.

    The format will work when managed natively, but it has been my experience that the best heavy treatment is transcode codec lossless 10bits before performing the heavy entry or color correction. I always cut or rough before entry or color work. The first edit is almost always first or Final Cut with native images from the camera. I then export the best codec 10-bit available. Design of black magic has a codec 10bits good, free for Windows. On a Mac, I usually use ProRez 444.

    Once the project is completed I'm usually a codec without loss of archives before you compress it for web or final delivery. The Adobe Media encoder allows you to take After Effects projects or agency directly to a compression quality if it fits into your workflow. Direct to SOUL will win you the time if you have the means to archive the entire project. If you plan only to now the original film from the camera in the archives and the project files or the ability to compress the final Assembly for other delivery options on the road there then I would follow the Lossless coding workflow project. Compression of an original HQ is always faster than the compression of a project file.

  • What is the best method to add data to a file stored on a usb flash drive to avoid too many write cycles?


    I'm trying to store an important data on a cRIO sampled stream in the USB flash drive.

    I believe that there are two ways to add data to a file:

    1. open the file outside of the loop, then write to the file loop, then close the file outside the loop.

    Pros; More quickly and efficiently than the opening and closing of files in a loop is resource heavy equipment.

    Disadvantages; If the program fails partially through, all data is lost.

    2. open the file, write to the file and close the file, all in the loop.

    With the advantages and disadvantages as opposed to option 1.

    As my cRIO is finally deployed in a hostile environment and data are valuable and processing speed is not an issue of concern in this project, I'm leaning towards option 2, but after a few basic calculations that I realize that I'll be writing/opening/closing the file of thousands of times and I wanted to know if this will wear out the flash memory?

    My uncertainty is due to not understanding what happens when a file is opened written to and closed.  He writes the new data to new areas of the flash, or it write all data on top?  The latter would cause me problems not too long term!

    Any help gratefully received.

    A big thank you and best regards,


    The 'magic' is not in the File Format (PDM vs vs binary text), but in the "life" of the file.  This solution creates a file of 24 hours and maintains a different file for each day.  If the USB "dies", you lose everything you have not backed up somewhere.  If the program dies (or errors), you lose the data for the current day.  You end up with multiple files (which can be a more or less), but we must still make the trade-off between (duration) of the file and the file number opens (which relates to your concern for the longevity of the USB).  By the way, I suspect that a good quality USB key (it's what you mean, right?  Or do you mean a hard drive USB powered?  Comments probably apply both) can predict today to not die on you, everything just because you make a lot of reads/writes (of course, you could get in-a-thousand...).
