Optical character recognition (OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text. It is widely used as a form of data entry from printed paper data records, including passport documents, invoices, bank statements, computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation. It is a common method of digitizing printed texts so that it can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as machine translation, text-to-speech, key data and text mining. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.

I had this question after viewing PDFTK - filling this PDF but got an error.

After talking with the others on this project, we decided it's ok to have the final PDF as read-only and it doesn't need to be editable.

I ran the commands below I can populate the PDF but not the checkbox. Joe (if you're reading this)....is this because of the LiveCycle issue that the checkboxes don't get checked?  If it is, I got approval to buy LiveCycle. I'll get it and see what's going on.

I tried "No" for value, "On", "1" but I don't see the checkbox checked.

1. i-765 is the orig file

2. notsigned.pdf is the file I QPDF-ed to get rid of the password error message

3. Ran this pdftk.exe notsigned.pdf fill_form i-765.txt output OutputFilled.pdf

4. outputfilled.pdf is the populated PDF.
i-765.pdf
notsigned.pdf

Hi, do you have any shortcut for avoiding special characters in textbox?
im using this manual code:

Public Class Form1
    Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
        If TextBox1.ToString.Contains("`") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("~") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("!") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("@") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("#") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("$") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("%") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("^") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("*") Then
            MsgBox("Text contains invalid character(s)", vbInformation, "Invalid!")
        ElseIf TextBox1.ToString.Contains("&") Then

I'm hoping there's a solution for this problem.

1. I have the FDF that I want to use to populate a PDF. It's attached. It's i-765.txt

2. I have the PDF file. I got it from the INS site. It's attached here and called i-765.pdf

3. I ran this command
   pdftk.exe i-765.pdf fill_form i-765.txt output Output.pdf

but got this error

Error: Failed to open PDF file:
   i-765.pdf
   OWNER PASSWORD REQUIRED, but not given (or incorrect)
Errors encountered.  No output created.
Done.  Input errors, so no output created.

I'm using ABBY OCR https://www.abbyy.com/en-us/  to read PDF files and parse some fields from it and then using C# code, I store the data in the database.

This is what I want to do:

I have some PDF files but they're forms. As it is now, we download the form and fill the form. For example, fill first name, last name, address, etc. Then we scan it or fax it whatever.

I want to read the entire PDF file and display it in a web page. Along with the image (if it exists).  Then, user fills the form online. For example, read the PDF file using OCR and display the same exact file on a web page, then save the entire form, print, etc.

Is this doable?

Edit: Maybe I should have the same fields the PDF form has on a web page. User fills the fields and somehow I plug those field values into the PDF?

Edit: I've attached a sample PDF form i like to process.
i-765.pdf

Hello,

What factors determine the quality and accuracy of OCR (optical character recognition) and is there much variability among different OCR software?

If there is variability in software, what applications are best (both free and purchased)?

Thanks

due to a recent hard drive replacement, I've lost the scanner tool and sharpdesk desktop software for scanning from our AR-M257 to my desktop unit. Is there a current software that I can download and install. I cannot find any disks in house for a reinstall ?

I have a client that has no electronic backup files for hard copies of booklets that require periodic changes. In fact, the problem is we don't know what format the original was created in. Some of these books have been around for years. We have a an old xerox scanner utilizing 'Document and Scan MakeReady' version 3.0.0.16 software. We don't have the CD. It doesn't appear to be available - I assume it's really old. It is running on a Windows 2000 Pro PC. The value of this existing software, is it's ability to allow edits from a received  scan document without changing the original format. At this point - after edits, it can be printed prior to having to save it to a file format , like PDF or DOC. In other words, it allows you to cut/paste changes without altering the original format.

Does anybody have a low cost solution providing the above functionality? Is there an OCR out there that will allow you to make changes prior to committing to a file format.

Here is the Script courtesy of Brooks Duncan at Document Snap and MacSparky.

I have run it on about 500 files and it mostly runs OK but it has failed about 30 times. Do you think that the delay needs to be increased? Is there anywhere to look for why it failed?


tell application "PDFpenPro"
      open theFile as alias
      tell document 1
            ocr
            repeat while performing ocr
                  delay 1
            end repeat
            delay 1
            close with saving
      end tell
end tell

Hello and Good Morning Everyone,

          From a previously closed post, I found out I can scan a text document straight into MS Word by using either ABBY Finereader or Paperport.  At this point, I am interested in knowing which program would work best for achieving this goal.  Any shared thoughts, suggestions, or tips will be greatly appreciated.

          Thank you.

I'm trying to  get OCR working using YAGF.  I read this is what Google used to scan books. I tried scanning a cookbook page and it gave me nothing.  Then I scanned my mom's harlequin romance book so there were no pictures.  That didn't work either.  Any guesses?  This is using ubuntu.

Can a Fujitsu ScanSnap iX500 use OCR to specifically NAME a file (PDF) as the value found when scanning?  For example, it we have a stack of invoices, all formatted the same with the Invoice Number in the same location, can we scan those and ask ScanSnap to name each individual scan page based on the value of the Invoice Number?  (I.e. Inv123.pdf, Inv456.pdf, Inv789.pdf)

Alternatively, I am more sure that we can make a PDF SEARCHABLE so that we could SEARCH within each document for a given invoice number... (i.e. search ALL PDFs that contain INV456)).  Only problem is, that would be slower than simply eyeing down a list of filenames...

Best way to scan and file similar documents?

Thank you!

- Numerous PDFs in a network folder, or to be pulled into the solution via a network scanner
- Need to read the bar code and extract the 5 pieces of data for indexing. OR, OCR portions of the page with the same data as in the bar code.
- Use this data to store the document for search and retrieval later - methods may vary. Would like documents placed into folders by the date in the bar code.
- Some sort of compression or load into a database is preferred to keep file size down.
- Windows or Linux based
- OpenSource only: I want to get my hands dirty with it.

Any ideas?

Hi Experts

Could you give a way on how to configure a "price reader device" - used in supermarkets f.e. ?

img_leitor

I guess that for the use it has to take a formated file with codebars/ prices, maybe the file format is  
defined by the device manufacturer. Once the device read this file (by USB f.e.) the device reader use could start.

Isn't it?

Could you clear?

Thanks in advance

Does anyone know of a way to increase the font size of PDF so that a 5pt document prints out in 10-12 pt font?  The attached page is 1 page of a 476 page document.

I tried converting it to Word and Excel, but those aren’t viable options when you think of the time it takes to OCR the doc.  Also, the output is horrible and there are so many possible mistakes, it doesn’t bare thinking of it as an option.

I don’t think there’s a way to do it, not even zooming with a copier works.

Hi

I'm looking for a solution that will OCR and index scanned documents for retrieval later by searching for key works or numbers.

Are there any industry standard programs for this sort of thing?

Thanks

Has anyone used this software?  I'd appreciate any comments anyone can offer - I can't find a single review on the internet, which is odd.
