• best practices to increase the speed of image processing

  Are there best practices for effective image processing so that will improve the overall speed of the performance? I have a need to do near real-time image processing real (threshold, filtering, analysis of the particle/cleaning and measures) at 10 frames per second. So far I am not satisfied with the length of my cycle so I wonder if he has documented ways to speed up performance.

  Hello

  IMAQdx is only the pilot, it is not directly related to the image processing IMAQ is the library of the vision. This function allows you to use multi-hearts on IMAQ function, to decrease the time of treatment, Arce image processing is the longest task for your computer.

• save an image in an image file and reloaded on another computer for the image processing

  Hello

  Can I save the image to an image file and then reload the file on another computer for the image processing? What type of image format should I save for it? Is there any loss of image if I do this? The machine with the camera sits in our lab, and I want to test the software on my own computer image processing. So can someone give some good ideas on this. Thank you

  Jane

  I assume you have the module development VDM and vision acquisition software going TO on your computer.

  So just use playback IMAQ and IMAQ save functions. BMP, png are good for losless save unlike jpg and jpeg2000.

  Hope this helps

• execution of inset in the image processing

  Hi all, I am using LabVIEW 2010 and the target computer is an Intel Atom N270 processor.

  I have a sub - VI dedicated to process the images acquired from a remote IP camera image. I want to deal with more than one camera in time. The question is: if I put my channel sub - VI like returning to image processing, image 'son' are protected? I know that these purple wires are only references to my images, and I fear that a second thread could change the reference at the beginning of the process chain while a previous image is processed at the end.

  I read in previous discussions on the change of each sub - VI IMAQ returning to achieve an improvement in the execution of the performance but the condition of incoming execution (in the vi containing the process chain) protects all references?

  Thanks in advance,

  Daniel

  Yes, Vision library is thread-safe. If you set your image processing environment VI (and all of its dependencies), you can process multiple images at a time, assuming you pass the different references to your treatment VI. Vision library lock a picture if it modifies the function you are calling.

• Can't get Image Processing VI of the Vision to appear in Pallate functions on the block diagram

  Hello

  I just installed the latest Vision after installing Labview 8.5, and it seems that I can open files previous .vi I did that use functions like "IMAQ label" and "IMAQ separation", and while I can access the section "Utilities of Vision" of the Vision, I can't find the button for the 'Image Processing screw. (See below)

  Thank you for your time,
  Santiago

  Hi Santiago,

  Is it custom screws you have created and added to your palette or programs that use the screw of the range of Vision and movement?  When you say that you have installed Vision, are you talking about software Acquisition of Vision or Vision Development Module?  Image processing screws are installed with the Vision Development Module.  Check out this KB to see if these are the screws that you always see.  I suspect that Vision Development module needs to be reinstalled.

• The Windows XP Task Manager does not display the names of process image

  I am running Windows XP with SP3. Image of process names are not displayed in the Task Manager, and in the column picker image process name, although is TICKING, is grayed out. I don't have the PID numbers. So I can't say what processes are underway. There are 57 processes running, that seems to be too many.   I tried running "tasklist > tasklist.txt"from command, prompt but it just flashes and nothing happens. " Does that mean I have a Trojan horse? What can I do about it?

  BDF

  That seems good enough for me - now, we know that your XP version and Service pack, System brand and model, BIOS version, the amount of RAM installed, the size of your paging file according to NEC, your system has SATA drives and a few other things.

  47 process may be OK depending on what you have installed and running on your system.

  Looking at my notes, I see that I thought a while back that the tasklist.exe program does not come with XP, but there's a copy on my SkyDrive for you to download.

  Here's how:

  Here is the link to my SkyDrive and you can get the file you need here:

  https://SkyDrive.live.com/?CID=6a7e789cab1d6f39&ID=6A7E789CAB1D6F39! 311

  You can download it and when you do, place a copy of the file in these folders (assuming that Windows is installed on your C drive):

  c:\Windows\System32

  When you see the files available for download, you can not see the file extension (.exe, .dll, .cpl, .sys, .zip, etc.), but when download you them they will have the right extension.

  When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, your browser is unable to save the file with an extension (by example, .exe, .dll, .cpl, .sys, .zip, etc) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

  You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called tasklist when the name of the file should really be called tasklist.exe (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

  Then, when you run tasklist > tasklist.txt, you should end up with a file tasklist.txt you can open it with a text editor.

  Even if you think yous system may be achieved a malware, it has never hurts to run these free scans before troubleshooting:

  No matter what you use for malware protection, follow these steps:

  Download, install, update and do a quick scan with these free malware detection programs (not at the same time) and remove all threats:

  Malwarebytes (MMFA): http://www.malwarebytes.org/products/malwarebytes_free
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

  SAS will probably report a lot of tracking cookies and you can just let him delete them.

  They can be uninstalled later if you wish.

  The scans by operating clean, restart, and then fix any problems.

• Improve the performance of processing image javaFx

  Hello

  I'm working on Image processing with javaFx. I think my code isn't effective favorite (with pictures HD, refresh is very slow). Because I am doing a 'for' on each pixel of my image every time I have to refresh it. But I don't know how else to do.

  So I need help to improve the performance of my treatment.

  This is my code:

  import javafx.application.Application;
  import jvafx.beans.InvalidationListener;
  import javafx.beans.Observable;
  import javafx.beans.property.DoubleProperty;
  import javafx.scene.Scene;
  import javafx.scene.control.ScrollPane;
  import javafx.scene.control.Slider;
  import javafx.scene.image.Image;
  import javafx.scene.image.ImageView;

  import javafx.scene.layout.AnchorPane;
  import javafx.scene.paint.Color;
  import javafx.stage.Stage;
      
  public class Example extends Application {
  
      private Image src;
      private WritableImage dest;
      private int width;
      private int height;
       int value = 0;
  
      @Override
      public void start(Stage stage) {
          AnchorPane root = new AnchorPane();
          initImage(root);
          Scene scene = new Scene(root);
          stage.setTitle("Demo processing");
          stage.setResizable(false);
          stage.setScene(scene);
          stage.show();
      }
  
      private void initImage(AnchorPane root) {
          src = new Image(
                  "http://mikecann.co.uk/wp-content/uploads/2009/12/ScreenHunter_02-Dec.-10-19.41-1024x484.jpg");
          width = (int) src.getWidth();
          height = (int) src.getHeight();
          root.setPrefSize(800, 800 + 50);
          ScrollPane scrollPane = new ScrollPane();
          scrollPane.setPrefHeight(600);
          scrollPane.setPrefWidth(1000);
          dest = new WritableImage(width, height);
          ImageView destView = new ImageView(dest);
  
          scrollPane.setContent(destView);
  
          root.getChildren().add(scrollPane);
          AnchorPane.setTopAnchor(scrollPane, 0.0);
  
          Slider slider = new Slider(0, 255, 1);
          slider.setPrefSize(800, 50);
          slider.setShowTickLabels(true);
          slider.setShowTickMarks(true);
          slider.setSnapToTicks(true);
          slider.setMajorTickUnit(1.0);
          slider.setMinorTickCount(0);
          slider.setLayoutY(700);
          slider.valueProperty().addListener(new InvalidationListener() {
              @Override
              public void invalidated(Observable o) {
                  value = (int) ((DoubleProperty) o).get();
                  color();
              }
          });
          root.getChildren().add(slider);
          color();
      }
  
      private void color() {
          PixelReader reader = src.getPixelReader();
          PixelWriter writer = dest.getPixelWriter();
          for (int x = 0; x < width; x++) {
              for (int y = 0; y < height; y++) {
                  Color color = reader.getColor(x, y);
                  double red = (double) value * x * y / (width * height) / 255;
                  double green = color.getGreen();
                  double blue = (double) value * ((width * height) - x * y)
                          / (width * height) / 255;
                      writer.setColor(x, y, Color.color(red, green, blue));
                  }
              }
          }
  
          public static void main(String[] args) {
              launch(args);
          }
      }
  

  And that's with full HD picture:

              src = new Image(
                  "http://www.freedomwallpaper.com//nature-wallpaper-hd/hd_sunshine_hd.jpg");
  

  As you change each pixel independently, there really is no other way than to use a loop through the pixels. Working directly with the pixel data, rather than use setColor and getColor (...) (...) seems to give some performance enhancements. And there are some general performance enhancements, you can use (reorder the loops, calculate the value used repeatedly, etc.). The performance of this version seems acceptable on my system:

  What is my camera taken in charge by National Instruments?

• refnum image processing

  I want the camera to stream to USB (buffer image0) with treatment in time real simple image (image1 buffer).

  After a treatment, I want to copy the image to another buffer image2.

  However, I have observed some interference between the pads.

  For example, I copied image1 image2 buffer. Whenever image2 buffer has been modified, image1 is also changed.

  I suspect my mistake in the refnum image processing but can't find it.

  Before posting my code shot, I want to check again with your comments because LV is not installed on this computer.

  Anyway, what is the rule in the definition/treatment image buffer?

  It is desirable to define the new back buffer image whenever I changed the image?

  I found a few examples of creating image inside the loop buffer without deleting the refnums.

  Is it safe to the memory of the control system?

  What I picture reference must be transferred with shift register?

  labmaster using LV2011 (no SP1)

  What image of buffers are you referring to the IMAQ Image?

  If so (or if not possible), these aren't the sons of Norway in labview, they are more like pointers than a thread that keeps the sata, so if you wiring buffer image 1 in the image of the stamp 2 make you actually point towards the same area of the image, copying data between buffers, there is a function of copy IMAQ This puts the data to the image specified by buffer 1 in the space of the image indicated by buffer 2.  (I say space image of table instead because IMAQ images are more complex than just a chunk of memory).

  Hi brad.

  Yes. You can use the analysis tools to straighten and crop your document. Here is a link to a new tutorial. The key to activate the sliding options recovery is to choose the option of the camera Image in the drop to Enhance, and gives you tools to set the correct page for smoothing areas.
