• 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.

• 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).

• 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.

• Live Image processing

  Is it possible to perform image processing (sepia, vignetting) until the photo is actually taken.

  For example: Instagram Live Imaging.

  Thank you

  Not with the NDK 10.0.4.  It should be possible by the time launches BB10 or 2.1 takes place.

• Image processing failure: error code: 1004

  When you export to DropBox of Lighroom I get this error: image processing failure: error code: 1004

  99% of the time the images for export to the correct location and look good. But the error always comes to the top. And every now and then photos are not really exporting.

• Problem with the display of the images after image processing

  I need to make a picture of the process (of getting some info) but after that I'm doing original I can't print the original image.

  

  

  The default value of Type of Image is grayscale. You must create the buffer of type RGB (U32).

• execution time varied in image processing

  Hello

  I designed a vi to process the images eyes and calculate its Center. However I seem to be getting various run time sometimes 100 ms sometimes > 200ms. I used the structure of flat sequence and timers to measure the runtime of the vi. I had a few parallel processes and had forced sequential streams using error hydrants. But the problem still remains. I thought that the problem could be due to different images of entry but the execution of the same image again and again still the same problem poster. Can someone tell me what is the cause?

  Running code on a Windows system is NEVER deterministic.

  That being said, the code in a way that can be allocated in advance all the memory of the design will be an important step to improve performance.

  Playing with priorities can also improve things, but you can easily spoil if you use priorities in a bad way.

  In addition, applications running in parallel will induce the unknown system resources (CPU, memory, interfaces,...) and therefore lead to greater instability.

  If you really have a hard cap for example loop iterations about the jitter (e.g. must not have a jitter > 1us), the only way to address that moves to RT or maybe even of FPGAS (depending on the complexity vs interfaces vs knowledge/skills).

  If determinism is required for the material e/s if it is single point (as in control loops), material clocked IO and manipulation of the data packets in the application is sufficient for 99.99999% of all applications.

• In almost real time image processing

  What is the best way to implement almost "real - time" treatment of image with two usb cameras? Capture, process, showing results and then capture, process, etc. until I chose to stop the program. I use LV with vision development module 8.6. What function can I use to capture the image?

  With LabVIEW 8.6, you can get the driver NOR-IMAQ for USB cameras .  It's really similar to the other drivers IMAQ, but examples are provided in this knowledge base.  To use several cameras, you will use just two copies of the screws.

  I'm not sure if you need more information than that, but let me know if you have any more specific questions, with which I can help.

• Trying to leave original in Image process Pro

  Are JJ, you there?

  When processing images in Image Processor Pro (e.g. resizing), the software seems to be remove their location files originals and place a new resized version of the image in the folder I specify in the settings.  I want PPIS to leave intact original images and place the copy resized in a new directory, which I specify, but I can't understand the to do.  The check box for the "Keep the Original file" option is grayed out.  Currently, I'll have to make backups of all images before processing in case something goes wrong.

  
  I feel I'm missing something but don't know what it is.  Any suggestions?

  
  Thank you!

  Default image processors scripts do not change the image source files or delete them.  Image Source files are opened then duplicated and the duplicate is changed and a new image file is saved using the save the options you together and the place that you set. If the output file is the processor would add a unique suffix for the name and save this single file.  Image processor only save new files it does not overwrite files. After registration, the document is closed. If more files need to be saved for the open source file it is duplicated again and the next new output image file is saved and closed.  When all output files are saved to an image the image source is narrow and the next source image is opened and processed when all sources of images have been processing the image processor closed the last source image and outputs.

  If the source files are deleted something is wrong.  X wrote contact IPP / / written by [email protected].  I see some code for intangible assets that can delete files from source I think.  It can also be an Image of the files removed from the list processor log file.

  If (! retainOriginal & file.absoluteURI! = outfile.absoluteURI) {}

  LogFile.write ("Deleting the original file" + file.fsName);

  try {file.remove () ;} catch (e) {}}

  }

  doc.activeHistoryState = historyState;

  };

  by default retainOriginal is true, however if you have an oid currupt saved settings it may be set to false.  My option is grayed out and is verified. Try using the reset button.

  

  ImageProcessorOptions.getDefaultOptions = function() {}

  var xml = not defined;

  var f = ImageProcessorOptions.getDefaultOptionsFile ();

  If {(f.exists)

  XML = ImageProcessor.readSettingsFile (f);   <----- this="" read="" old="" settings="" so="" try="" te="" reset="">

  } else {}

  XML = ImageProcessorOptions.DEFAULT_XML.copy ();

  XML. Input = XML (")");

  XML. Input.@source = "folder";

  XML. Output = XML ("

  ");

  XML.output.@Path = Folder.desktop + ' / ' + 'output folder ';

  XML.output.@subfolder = true;

  XML.output.@keepStructure = false;

  True XML.output.@retainOriginal=;<---------- if="" no="" settings="" file="" default="" is="">

  Also, if you include ongoing Actions to consider actions.  You can run a script that could possible to delete files.  A file deletion I think it should be a script.  Photoshop is not a file editor it may overwrite a file, but not to delete a file. You can manually delete the files to open and save file dialog boxes.  Photoshop has no functionality of file delete AFAIK.  Bridge can I think move and delet file I use much the bridge.

• Get images processed green issued AFTER what they are downloaded

  Well, I have a 'fun' one...

  So I pocess my RAW (NEF) image with first lightroom, then photoshop (the two CC).  My finished images looks good, then I save it in JPEG format.  It always seems well.  I upload them to Facebook, he STILL lookes fine...

  BUT... when my model downloads exactly the same image (JPEG) of my OneDrive (it seems still well on his hard drive), and then it downloads on her Facebook, it turns green/yellow.  Also, when I upload the image to some websites, it runs as green/yellow (with Facebook and my own Web site, no problem, but other sites like "myglamfolio.com", it turns green when I download).  Also, when I just put the image on a USB key and try to play on my TV, it turns as green/yellow.

  On top of that, the problem is solved when I resize the JPEG with BDSizer.  (all diminensions)

  This problem occurs only with images that are being processed with my Lightroom and photoshop CC.

  See below for my version on Facebook, and then after it, the version of my model on his Facebook.  It's THE SAME EXACT of the image file, but hers is downloaded through OneDrive.

  

  

  I really hope someone has a solution, because it is unprofessional of me to deliver "defective" my clients images.  My client thought that it was my picture finished and had not she tagged in his photo, I never would have known that I have provided his images "defective".

  I'm a little frustrated liiiiiiitle, but I appreciate all the help I can get.  ;-)

  I think that the default color space used by LR from the picture edit in Photoshop is ProphotoRGB, so, Yes, in Photoshop, you need to convert (not entitled) to the color space sRGB before saving it as a jpeg, if images are to be used on the web. As an alternative, you can use the "Save for Web" option that does all this automatically for you.

• ID CS4 automating Image process Question

  Hello

  I have an old catalog given to me by a customer for the redesign and update. All the old images were jpg and is poorly calibrated. I corrected all the problems of image in PS with a lot of help from the controller > Batch feature. I saved all the correct images as eps files high resolution now for the final output. Is it possible in InDesign somehow automate the process of restoring links all the new images?

  All images have the same name file as before, but with the new extension of the eps. Of course, this breaks the link since it is looking for the old version of jpg. Did someone knows a way to automate the process of re-connection ID since all file names are always the same? (Except the extensions it is)

  I can do it one by one, but there are a ton and it will take time... Thanks for any advice.

  P.S. I'm on ID CS4 on OS x 10.5.6

  http://InDesignSecrets.com/relink-from-one-image-file-type-to-another.php

  But, why would you use EPS files? TIF or PSD would be the best choice.
