Creating a good abc file for OCR

Hello

I'm looking to generate training for my text VI recognition data programmatically. I found a VI of pre-existing (https://decibel.ni.com/content/docs/DOC-26398) which takes a string and generates a .abc. However, the results were not too accurate. A slight increase in the rate of detection was obtained by adding duplicate characters but in different size. However, 'IMAQ OCR Train' is capable of managing the 255 characters, so I can't create an enormous amount of characters for the training data or I am confident that the result would be that much better to make it. I was able to create another .abc file by manually setting the characters in "Vision Assistant" VI, but the difference between the methods was an important place and this one was a lot more reusable time and less.

My questions are the following:

How could I could create a better set of training data using the attached VI?

Would it not possible to generate multiple abc files and combine them into one?

I think you can merge files set character in NI OCR training interface.

  • Create a very large file for printing

    Hello world

    I need to create a VERY BIG file for printing.  The final print will be 148 "height x 124" wide. I tried to find a way to build it. I created all the graphics vector and enlarge the photos to a size that can be included, but whenever I try to create this file it fills the disk of my work and I can't perform no action.  I also tried to create in Illustrator, but I'm not too good with Illustrator that I am Photoshop and honestly have NO idea how to proceed.

    Anyone can guide me please thanks to this? It is due to this evening and I'm really at a huge loss.

    Thank you in advance!

    OK this isn't a huge size - but if you are struggling on your system with it, you could do like Mellissa and build it in stages, thereby minimizing the layers in the final assembly.  You could also work in 8 bits rather than 16 bits to assemble the image print - it will be half of the memory required.

  • How do I create a small PDF file for the web with fonts embedded in the InDesign files?

    How can I actually "convert" my files of 100 pages, produced magazines in InDesign (300 dpi, CMYK, prepress ready images) to PDF size reasonable to publish on the web. I tried "smaller" size of the file in Acrobat, but it does not incorporate the fonts and images are very unclear. I tried printing of high quality, but the file size is too large (100 + MB). Can someone point me in the right direction? My company said I need to get a PDF (below 38 MB) file to the webmaster to display. I asked the administrator of the site - he had no idea of converting to InDesign.  Thank you!

    You can start the press or high-quality Print PDF you make when you run the optimizer, as both will be incorporated, fonts and images high resolution. You don't want to have courses for your magazine of font substitution.

    If you have converted the images to CMYK before placing them, it matter which two presets you used for the base file, but if it's RGB, high quality print Prest will abandon them this way, which will also result in a smaller file. You can also convert the CMYK to RGB in Acrobat, if necessary. Do this before you re - sample.

  • XP pro sp3 run asr, but didn't start; files for the recovery diskette could not be created

    I had previously asr has been successfully run on the same configuration but have decided to update the recovery data. I tried to restart the asr by clicking Start, all programs, accessories, system, backup tools. The Backup Wizard appears and I clicked on Advanced Mode. Then followed the backup utility page, I clicked on the ASR Wizard. The next page has been the preparation of Recovery Wizard, I clicked next and was presented with the option of backup destination and, after finishing the backup destination, I clicked Next. My page was last option; End of the ASR Wizard, I clicked Finish. Backup went into his usual preamble but almost instantly a warning box came up with the message "files for the recovery diskette can not be created." I am running xp pro sp3 as I had been for the creation of the previously successful GDR.

    I also tried using the Backup Wizard and I clicked on backup all information on this computer (this option automatically provides ASR) and followed the instructions of the wizard through to the end and the failure has been the same.

    I found a solution to my problem of ASR. If I was not able to create an asr backup, I was still able to run Ntbackup. I've saved my OS drive then ran repair with the XP Professional installation cd. Backup ASR works now.

    OK, I had to reinstall all them that updates the Knowledge Base Microsoft and also all the Service Packs. One or two of the plug-and-play applications were a bit annoying, but be as I have all the installation cd, other than being tedious, have all been re-installed and the system is now as good as new.

  • create an exception in avast for the nsemail.html file in the temp folder

    I was pulling out my hair trying to find if there could be anything in the temporary files that I have to keep the last few weeks. Then I came across this: "the release of Avast 10.3.2223 (we think it's this version) has resulted in questions with avasts prevention of Thunderbird.

    Matt, thanks. I read your blog post. I need to replace my HD and I've been fretting over if I have to loose important data from the temporary files. Apparently not. When I talked about ccleaner, it was in the generic sense. I avoided ccleaner because I thought it was a big hammer and some data that he brags about getting rid of I really want to continue. I know that I can choose what remains and what is happening, I'll have to give him another look. Once again thank you.

  • can I create a DLL file for labview that has DLL library with inside?

    Hello everyone,

    I am developing an application for the cards PCI devicenet in labview (beginner to labview) environment.  Is there a DLL file for the PCI card from the provider. But it's too complicated for a beginner to call each function in the DLL of labview. Therefore, I'm trying to re - use a VC ++ program (working properly) that calls some sellers DLL library functions.    To do this, I created the DLL file which includes all headers and libraries the provider DLL, as indicated in the attached figure. But I couln can't see the effect on the device. is it possible to create a DLL file for labview that has DLL library with inside? If this is not the case, how can I implement the program shown in figure?

    I would like to wish a huge as to advance.

    It is not something I have a lot of experience in so I don't know all the details of the restrictions or requirements etc - but it is certainly possible to create wrappers for the dll and then use them in LabVIEW - this is sometimes necessary to convert some native types/data structures in C/C++ into something that you can switch to your other DLL LabVIEW.
