Look for the object on the image (or video)

Hello friends!

invite me please!

I want to "teach" my VI to choose object on the image (or video). My VI needs to read the information (text) of certain documents with the OCR function. But I have to create the KING myself and my VI works very bad because documents can move and the KING gets bad. So I want to my VI will find text itself and the value of ROI on this text. Is he capable?

Any help and example will be thanked!

Something like that:

First detect the two edges of the driver's license, and then calculate the intersection between the two edges, then setting coordinate system and after this KING repositioning to OCR stage depend on the coordinate system:

OCR now works also for image in rotation:

Take a note, Straight Edge (Rake) will be working for 8-bit images. Because RGB is not supported, you will need to convert your color to grayscale image.

    Thank you for your help.

    Ahhhhhh, okay. Including this one after more digging.

    Here is the answer from another post. I hope this helps someone!

    If you specify an absolute url of file, or you extract content from a server that does not host the content, you can manually update the _edge.js file to specify the directory:

    (function ($, edge, compId) {})

    image folder

    IM var =' images//';

    Just be wary if you re - publish files, you will have to redo any custom changes.  I do it for the projects off-server and it works fine as long as you make all changes in each JS file where you specify the exact path.

  • File missing for the image of the office - so cannot delete!

    Hi all

    I like the image of the desktop to select random pictures, but eventually he travels to present an image of an old Mac OS "crystal cave" - that seems very pixely and terrible, and he stayed stuck and will not go.

    I have searched for it with a finder search, shows up no results, and I also watched in the real image of the desktop folder. It is not there anymore.

    My uneducated theory, is that the image somehow was inherited from Mac since I had, possibly attached to my user. Although I just checked now and it is also available to the user profile on my wife. The reason why it is so pixely is probably because it does not refer to an image file - like what is happening in publishing computer programs when the link is cut between the elements of layout and image files.

    Any ideas?

    Thank you

    Look in your Finder > go > go to folder, copy and paste:

    / Library/Office photo

    look through the images and delete the file low resolution which is to play with you.

    Turn it back on.

    You probably need to recharge the device drivers and camera control software (usually included
    with the drivers and installed at the same time).

    Login as an administrator.

    Double-click Control Panel / Device Manager - Imaging - writing down of the brand and model of camera.
    on this subject and on the tab of the driver is version. Now, click on update drivers (who are unable to do anything as MS
    is far behind the pilots of certification). RIGHT click on the camera - UNINSTALL - REBOOT - it
    will update the driver stack.

    Now, go to the system manufacturer's website and download the latest driver for the camera and the other related camera
    software (if not more recent get the same).

    Download - SAVE - go to them and RIGHT CLICK - RUN AS ADMIN - reboot after each driver.

    Manually look at the sites of the manufacturer for drivers.

    Installation and update of drivers to 7 (update drivers manually using the methods above is preferred
    to make sure that the latest drivers from the manufacturer of system and device manufacturers are located)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    Then let windows updates on however prevent loading of drivers who are often older than the
    those that you have installed. If updates suggests a pilot and then HIDE it and watch manually to see if their
    really is a more recent version (at the time system manufacturer and the sites of the manufacturer of the device).

    Note that you can work with two screens and drag and drop the image to display on the other window.

    I think you mean working temporarily with the window enlarged image without displaying all the tools and panels.

    See:

    Panels and bins in Photoshop Elements

    My advice: take the time to read the above help and especially to look at ways to maximize this window if you are on Mac or Win.

    Set your preferences in the Edit menu to "allow the floating windows in expert mode.

    Use the "tab" on the keyboard key to hide or show your panels and tools quickly.

    Hello world

    Never done this before, are looking for the part number or a screen for the z24 1130 above

    help please.

    Hi michael,.

    In my opinion, you should contact an authorized service provider. Why? Guys can you tell the exact part number and order a new replacement screen for you. On the Toshiba site, you can search for them.

    Alternative look on eBay. Here you can often get second hand spare parts. The screen is an expensive item so maybe you have a little luck on eBay.

    Hello

    HARD drive recovery can not be downloaded.
    You can not download the recovery disc as well.

    Generally, recovery disc HARD must be available on your laptop and you should be able to start this pressing F8 at the beginning of the initialization.
    Simply said: turn on the device, press F8 immediately after the laptop was turned on maybe you will have to press F8 several times in the line
    Then choose fix my computer and then you should see the drive HARD recovery option.

    If this is not available (no matter why), then you must create a recovery disc using called Recovery disk Creator tool that must be preinstalled on the laptop.

    If you are not able to create the recovery disk then you can order it from here:
