• Image processing failure: error code: 1004

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

  Under which it lists all the images that I export.

  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.

• 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?

  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).

• 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.

• 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.

• Why is-C code so much faster? (Image processing)

  Hello!

  I'm working on a larger application but I reduced to show you a problem I encounter at the beginning. I join all the files needed to run.

  It is simple rgb2monochrome that I implemented in C code algorithm and code LabVIEW. I have not now why the C code is 4 times faster.

  In the code C transfer tables with pointers so I'm working on a given memory area. I thought that LabVIEW can be slower, because it creates unnecessary copies of berries. I tried to solve this problem with Structure elements instead and value reference data but no effect.

  I also tried to change the tunnels in the shift registers in some places (read in optimizing LabVIEW Embedded Applications). I changed options in the execution of the subVIs properties and I created EXE application to see if it will be faster. Unfortunately I can not yet reduce the difference time of execution.

  I know that my algorithm can be better optimized, but this isn't the main problem. Now the two algorithm are implemented in the same way (you can check in cpp file) when it should have a similar execution times. I think I made a mistake in the LabVIEW code, maybe something with memory management?

  And I know more... Maybe nothing wrong with LabVIEW code but something too good in C code ? It is 64 b library, implementation of usual way without forcing the parallelism. Moreover I brand performance in the thread of UI in COLD LAKE. But perhaps nevertheless CPU manages this function with multi hearts? I have 4 cores then the difference in execution time would be good . But it's impossible, right?

  I know that the notice that LabVIEW is sometimes slow, but approximately 15%, not 4 times. So I had to make a mistake... Anyone know what kind of ?

  Kind regards

  Well, here are a few things that make faster LabVIEW code, there are other improvements that could be made, but I would need to do several tests to see if they are better based on your input data.  First of all, I would like to enforce the VI Inline, not subroutine.  Also, I'd work with arrays of data instead of scalar values.  Also, you know the number of rows and columns because it is the size of the array, why keep this information?  Oh and if you are working with curls you can try parallel for loops to work on more than one processor at a time.

  And also, I'm not sure that all this work is in any way necessary.  If you have a double and turn it into a U8, it will be 255 If the value was greater than that to start with.  Attached is an updated release with several possible options to try.

  

  Oh and another improvement, why are you even unbundling the data in Unbundle_imageCPU1.vi?  Why not work with this table 2D-Red Green Blue?  I realize that even VI is called in LabVIEW code options both C but with LabVIEW just deal with other data could make faster together.  In particular, in view of the fact that regroup you after you're done anyway.

• 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.

• 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.

• 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).
