How to segment joints cracks between them using the wizard of vision?

I built an application that processes the images taken from a camera high resolution with IR lighting. I noticed some cracks in the pavement could unite or are having joints that are cut into the concrete or ashalt. I need to distinguish between the cracks and joints so that I can classify and record their location on the image for a worksheet. I saw where someone has used the segmentation of the circular basin of separation is opposed, but it works for cracks (lines) so? If not is there ideas for 'disconnect the cracks in the joints. I have attached my script assistant of vision and an image of the sample. Thanks in advance for your advice.

I tried the features of the morphology and the problem is it joining a crack for joints, if it was them that intersect and then counts as a single object/shape. I ended up finding a solution really good. I used the detection of edge advanced prior to dilation image, then use those points to detected lines to extract the joints and obtain the necessary information (width, length, position), then use the positions draw black pixels on the joints on the binary. This allowed me to get the information that I needed for the joints and also remove them from the binary image so that I can treat the cracks by flying over in he picture. Now, I just need to find a way to get some of the other object that the threshold is removed so that I find myself with just the cracks. Thanks for the help. Its always good to get some ideas from someone looking to another direction.

  • Move between photos using the mouse scroll wheel in the library module

    I've recently upgraded to LR6.4, in the library, to the Magnifier module, I can't move between photos using the mouse scroll wheel. When I point the cursor on the picture, I get a "magnifying glass". The only way I can move between photos is to click on the film. I was able to use the mouse scroll wheel to move between pictures before. Help, please.

    It doesn't matter whether or not this option is displayed. Just open the preferences and restart LR should dissipate it.

  • If I use the wizard to transfer settings and files on Windows XP, it will keep my Microsoft Office 2007 activation activation, or will I have to reactivate the program?

    I just need to restore my default settings to get my games that I LOVE to play the work; It is a windows registry problem, I think. I have my last installation of my program installed now, and I don't want to have to buy the program again to re - install (Office 07). If I use the wizard, it will keep on, or will I need a new drive to re - install?

    If you reinstall to factory settings, you will need to reinstall all the programs you have installed.
    You will lose all data
    You must run MSUpdate before installing Office
    You can re install Office as often as you want if its on the same PC, the worst way, you will have to use an online activation, and if it's a retail edition, you can install on any PC you own whenever you exceed the number of work PC allowed by your license.
    It is not recommended to use QUICKLY to desktop settings
    (I assume you have the cd/dvd as well as its key office)

    Finally, what makes you think that it is a registry problem?

  • How to make the script a buttons previous and next to navigate between fields using the navigation sequence?

    I want to put in "next" as well as "Previous section" buttons on the top of my page, aside from the arrows in the table of contents. I put a browse sequence. But I am unalbe to describe the buttons. Can anyone help please.

    Thank you.

    Hello

    You're definitely on the right track. The problem is that you cannot use a path "hard" for images. It may work for the subjects to the root, the directory images can exist. It may not work for the subjects, because the correct path would be something like '... /... / Images /'.

    In addition, you must add the images as baggage files to your project. If you only use the images in a script, RoboHelp does not recognize them as resources.

    I've updated you above the article. He now understands how to use images like browse buttons in the sequence.

  • Satellite Pro A200: How to create Dual boot; Vista & XP using the recovery CD

    I just bought a laptop Satellite Pro A200, which was supplied with the product for Vista and XP Recovery discs.
    The license specifically Vista also XP licenses.
    Can I set up a dual boot so that I can boot to Vista or XP? If so, how?

    I would also like a third boot, Red Hat Linux 9.
    Any comments?

    Hmmm. Usually it s possible to use two or more operating systems on the computer, but as far as I know the Toshiba Vista recovery CD formats whole disk when installing Vista and this will lead to the loss of the OS installed.
    I m not 100% sure on the recovery of the newest XP CD called RECON doesn t CD include an expert mode which allows to choose between the different partitions.

    So I guess that each use the recovery CD will format the HARD drive and erase the installed data. But of course, you can try to install the two BONES and to check if the restore XP CD allows to choose the second part of the installation of the OS.

    If it does not, it seems that you will need to an original XP from Microsoft CD or the original CD of Vista to use the two BONES.

    Best regards

    I want to create a "run way asynchronous step VI" using the API TestStand in LabVIEW.

    Navigation on the details of the step and the properties of the object, apparently, that it is a type of 'special' step that is actually a SequenceCall.  However, I don't see how to access the data contained in this type of step.  I enclose my current VI used to 'Browse' the data for reference.

    Please advise on how to create this step.

    Hey LVB,

    I'm sorry, I didn't know that you always wanted to use the "Use the Prototype sequence" checkbox option.  In this case the attached code should demonstrate how this can be accomplished.
