• Changing picture of edge detection

  Hello

  has the edge detection used to find the edge, I got on the threshold of the image to find the edge, I also do Canadian chicken market on image so try to save the image intact, using a copy of the memory buffer and imaq but that I have never, intact image seems to have the lines of research of edge detection and results appear on this also. any body know what is happening here.

  Thank you jake

  Hey Jake,.

  I made a small example here for you with a threshold instead of an edge detection. Basically, you need to do the copy imaq, before do you the processing on the original image, if the processed image will be copied. I hope that helps you some.

• HELP WITH SOBEL EDGE DETECTION VI

  Hi all

  As usual I need your help to complete my project.

  I am currently working on the Sobel edge detection using LabVIEW IMAQ Edge Detection VI.

  I did a VI for the same thing, but it does not give the result, I hope to have. I have attached the vi below and the images for which I wish to find the edges.

  Further, I'd be grateful if someone could help me understand the process that I found it difficult to understand the context of help for the same.

  With the best regards

  JALASHWA

  The first thing you will probably need to change would be your threshold to 0.  Currently you are throwing all the edges of a value of less than 255, which is that each of them.

• I can't change the discripter KING of the circular edge detection

  Hello

  I need to find the find of circle using the circular edge detection. Here, I need to change my KING. so I used the property Node display.

  But I can't change my KING.

  I've attached my VI file

  I understand that you want to change your return on investment... have you checked the link I provided in the previous post?
  -KING of the ways showing different coordinates, how you give their evolution?
  -simply by selecting the property KING will give nothing unless you draw something in the indicator of the image. For example, when you select the tool KING and draw something so the return on investment parameters will be passed to the property node.

• get the path generated by edge detection

  Does anyone know a good way to get points boundings or path of the path generated by the function of edge detection in the TextWrapPreferences?

  Thank you!

  Pieter

  Hey!

  Try this:

  mySel = app.selection[0];
  myFrame = mySel.duplicate(undefined,[0,0]);
  myFrame.graphics[0].clippingPath.convertToFrame();
  myFrame.graphics[0].remove();
  

  Select the image with a created clipping path and run this code. This will duplicate the selected image, extract a clipping path and delete the content.

• OR VIsion: Edge Detection, Auto Setup

  Hey,.

  I work with the NI VIsion Module and try to use the IMAQ find Edge.vi. If you are you using the Vision Assistant, you must enter the 'meaning', "Edge of polarity" and so on. And the more you are able to mark "Automatic Configuration", so that the Vision Assistant chooses the other options as the "core of size' etc.. Is it possible to use the 'Auto Setup' in LabVIEW? Because when you create a vi out of your script, the vi in LabVIEW is just a constant as input to the 'line Fit Options'.

  Thanks for your time

  Kind regards

  -Eye-

  Hi eyes.

  The automatic configuration feature is available in the wizard of Vision because it is very intensive and can be less robust in some cases. NOR does the packaging this feature in LabVIEW because NEITHER assume that users will be able to define a detection zone of edge suitable for their particular application which will be more robust without the need for these resources. So leaving the VI in an Express VI will allow you to use the automatic configuration for the edges to find tools.

  Kind regards

• Animate simple Collision in edge detection

  I'm new to lively edge and I created a game in which a player moves their character left and right on the screen, trying to avoid colliding with the other characters. I searched for a good and simple collision detection function/algorithm/plug-ins use to detect these collisions.

  The characters are all simple rectangles (convex?) and the other characters move vertically along the y-axis while the character of the hero can move left, right, upwards or downwards. I have 2 two questions that I can't solve right now:

  1. how to keep my character of heroes within the scene (I don't want him to go off the stage when the Player tries to move it left/right/etc... too far;)

  2. how to I detects collisions between hero and 20 characters or other character that drive up and down along the y axis?

  My thoughts are that inclusive would be all that is necessary for this game pretty simple because I don't have a lot of characters to check collisions and my characters are all rectangles. I stripped down so that two objects on the stage (a blue and red rectangle) and I overlap right now (should indicate a collision) and tried to implement the following code to detect the collision. I put this function in the action of compositionReady:

  var Object1 is sym. $l ("BlueRectangle");

  var object2 = sym.$("RedRectangle");

  If (object1.x < object2.x + object2.width & & object1.x + object1.width > object2.x & &)

  Object1.y < object2.y + object2.height & & object1.y + object1.height > object2.y) {}

  The objects are in contact with

  Alert ("Oops! You crashed! ») ;

  setInterval (sym (e), 35);

  }

  But it nothing happens when I test the project hosted in a browser. No alert occurs. What I am doing wrong?

  Once I understood how to apply the code to run the detection of collision for several rectangles that could collide with my hero character?

  How to set the interval to periodically check the collisions and what is refresh rate?

  Any help would be greatly appreciated!

• Measurement error of the County of edge by using the external sample clock

  Hello

  I'm trying to measure the number of edges (rising) on a square wave at 5 kHz with a generator function on a device of the NI PCIe-6363. I configured a channel of County of front edge of counter at the entrance of the PFI8 device. I use an external sample clock that is provided by the output of the meter of a NI USB-6211 housing channel. If I acquire for 10secs then ideally I would expect to see a total of 50000 edges measured on the meter inlet channel. However, my reading is anywhere between 49900 and 50000.

  When I use the internal clock of time base to measure the edges, the measure is accurate and almost always exactly 50000. I understand that when you use the external sample clock, the precision of the measurements is subject to noise level of the clock signal. However, I checked the clock signal is stable and not very noisy. Any reason why there is an error of measurement and how tolerance should I expect when using an external sample clock compared to when you use the internal time base clock?

  Also, what is best clock Frequency (with respect to the frequency of the input signal) when using an external clock?

  Thank you

  Noblet

  Hi all

  Thanks for all your sugggestions. I was using an input signal with a function generator which had a range of 8V. It turns out that the reduction of the amplitude to 5V solves the problem. I was able to get accurate numbers with the 6211 external clock.

  Thank you

• F-&gt; T amounting to edge detection

  Hello

  I am trying to understand any way or somethink, which detects the rising edge and the output value will be true (when the state changes from 0 to 1).

  So if the entry is 0, output is set to false. When the input is 1, output is set to false. Just the moment between 0 and 1 must be true to the exit.

  Are you all plese advice?

  Thank you, pelda

• Hardware changes not detected using a flash drive, the missing, system restore points tried every fix that MS can offer in Windows 7

  All of a sudden, I have several problems with my computer.  I can't not computer to recognize a flash drive.  Printer works in the same usb port.  I used Device Manager, checked the drivers, made every difficulty that MS has to offer, each difficulty that Dell can offer, but the problem remains.  I don't feel uncomfortable so I don't have to play with the registry.  I uninstalled the drivers and rebooted.  The only changes that I did before this happened was to uninstall and reinstall I-tunes.  The flash drive, I use would be defective?  When I went to the system restore, my restore points have disappeared, that was the point where I uninstalled I-tunes.  I also noticed that when I tried to detect problems with the resolution of the problems of hardware and devices, it says "material changes may not have been detected.  In detail, it also shows "there is no configured windows in a way never install driver - edition".  WHAT?  I know that windows IS configured to automatically install.  (Deep breath)

  Very well.  So I am at a loss.  Any suggestions?  Thank you very much for your time and your attention...

  Hello
   
  Welcome to the Microsoft community. I will certainly help you with the problem you are experiencing. To better understand the issue, I would like to ask you a few questions.
  1. What is the model of your Dell computer?
  2. that all measures tried on your own to fix this?
  3 have you tried to test the flash drive on another computer to see if it is faulty?
   
  This problem arises usually when the flash drive is faulty or the chipset drivers are in conflict with the USB drivers.  I recommend you to consult the following Microsoft article and check.

• C60 DVI input 3 Auto Detect using a DVI to VGA splitter

  Hello

  We install a codec C60 using a splitter DVI input n ° 3 for the presentation source (DVI - I male to DVI - D & VGA Splitter cable's female adapter)

  The DVI input source is configured as Auto-Detect.  Administrator's Guide confirms this seting automatically detects the signal is analog (VGA) or digital (DVI or HDMI).

  The problem is the codec can't really switch from one source to another.   We do not seek to send two signals at once, but rather stable wether VGA and HMDI will be detected by the codec according to the entry sends the laptop.

  can anyone confirm if this is a limitation of the codec, or bug in firmware or even simply impossible without adding additional hardware.

  see you soon,

  Mel

  Hello

  Yes, auto-detection works for me.

• counterfeit or detected used cartridge

  I installed a new set of inks in my C410B and since doing so, the black cartridge is not displayed the correct ink level it shows as empty. I get a messsage in the HP software indicating counterfeiting or used cartridge detected. No one knows how to fix because it's a brand new HP cartridge. Thanks in advance.

  Hi Robbie, it is likely that the msg is displayed because the black ink is almost empty. You should be able to 'OK' message and continue printing. More details in the links below...

• Trigger Adobe Edge Animation using the Adobe Muse?

  Hi guys,.

  Been trying to understand this for a few days now and have had no luck.  I have an animation that I created with Adobe Edge, and I am using an Adobe Muse button to trigger the animation.  Is this possible?  Any suggestions?  Thanks for the research!

  I did a little by making a button to animate dashboard instead. The only thing is that you must use timeline for the overview of the buttons and buttons on the edge connecting _self link within an iframe that is terrible.

  IMO avoid border links, unless they are binding outside the Web site.

• Extract and save all the channels of the PXI-5105 with 4 M of edge detection... Help!

  Dear collegaues!

  Please help me to improve my request, exhibit attached and sorry for my English.

  So my task is to extract and save all the channels (eight) of the PXI-5105 with 4 M of detection of peaks and sample rate 4 M with loop 1 sec...

  Entered all my channels are wiring detectors NaI with 0, 5... 1 microsec pulse (really) width and 0 kHz at not more than 40 kHz freq.

  Why I chose the registration of 4 M and the sampling frequency of 4 M namely? Answer is that I tested previously PXI-5105 40 kHz generator and pulse width 0.5 microsec. It works great and detection of peaks indicate 40000 pulses/s for me. If I set lower than 4M record and sample rate of 4 M, it is without work. In my honest opinion record 4 M and the frequency of sampling of 4 M are parameters very min.

  In the detection of peaks time present only 6 working channels... When I connected to diagram more 6 "detector.vi peak" - I see the error "...". out of memory... ».

  Advise me please, what needs to be done to it, it's all working well.
