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.

We want to develop an inventory application for a client.  They use Surface tablets to take handwritten notes which they later transcribe manually into Excel sheets.  We have an old application in Access which is close to what they want, but what it lacks is OCR.  We'd like for the client to be able to write their notes directly into a field.

From all that I've read and researched so far, it seems that Access 2016 does not have OCR capabilities, nor could I find add-ins which provide it.  The best I've been able to find has either been the OneNote API (writing notes in OneNote, linking to them in Access), or libraries for WPF (which would entail writing the app from scratch).

Has anyone seeing this done this before?  Any suggestions for accomplishing our goal?

Cloud Class® Course: Python 3 Fundamentals

This course will teach participants about installing and configuring Python, syntax, importing, statements, types, strings, booleans, files, lists, tuples, comprehensions, functions, and classes.

As part of a news research project I need to download a series of pages from a site to perform OCR on them.
The site is using PHP and JAVASCRIPT to which I do not have real acquaintance. I have tried to download the image  in order to OCR it, but all pages on documents only show the page 1 and not the following pages.

The page has a button to circulate amongst pages and the code on the inspect is:

<a id="pag_seguinte" class="muda_pag botaoLinha setaDireita" href="http://casacomum.org/cc/visualizador.php?pasta=06337.058.13733&pag=2" title="pg. +1" style="visibility: visible;"></a>

 
Can anyone help me on trying to circulate amongst the pages?

I need help creating traineddata for Tesseract.  We need to train it for Car VINs.  Linux server got it installed on V4 and I creayed a set of 12 pictures to work with.
In the end, it's to be used in PHP on a website. Everything is completed except it's not accurate enough using only english traineddata.

The existing documentation is too confusing for us.  

I am looking for more specific instruction or someone we could hire for a few hours to help on this.

Out traineddata is located in /usr/share/tesseract/tessdata/

Anyone has MSWord/editable version of CIS hardening guides?  
If not, appreciate if someone can OCR it to Word (I have problem attaching the PDF files here) as a number of free online ones are limited in
the number of pages that can be converted & boxoft doesn't seems to work well on my PC.

We have a multitude of files we need to OCR, some are images, others PDF. I can find tools which can do these one at a time, but need something that could do hundreds if you point the software in the direction of a folder full. I do not trust online converters as the docs may contain sensitive information. Please let me know of anything that may meet our criteria.

I am considering making a site that can auto-analyze a certain type of uploaded report, and instantly display the results as a PDF. There are various steps involved in the creation of the PDF and I want a feeling for the effort and technology needed for each step.

There are three different steps I will discuss here to see where I can use WordPress plugins and where I need to customize the functionality.

The uploaded report would be a merchant's monthly credit card statement, like the following snippet..

Statement Example
1) So, for the first of three steps, I need a WordPress OCR plug-in. Are there many options for that? Is the angle of the text a problem? I can not guarantee neatness. (I added the underlining to make it easier for me to read)

I imagine allowing an authorized user to upload a report. And i need this plug-in to convert images to some form of digital data, like a PDF or a CSV file.

2) I need a way to analyze that data, and wonder if there is a configurable WordPress plugin for this? It will query the items by the Description, then use the numeric values in the Number, Amount and Total columns for mathematical computations. There will be some mathematical steps performed on some of the data as it generates the output for the report.

The results should go into some format, like a CSV file

3) I need a report tool which can import the data results from Step #2 and apply them to various pre-designed fields in the final pre-designed …

I need a tool I can use to digitize a report, like the one attached here...

Report
Will this kind of report get a 100% successful conversion rate?

Eventually, I need the tool to be part of my website, but I have not, as yet, chosen my back-end technology. For now, a simple Mac based tool is fine, just so I can hand convert a report that I can start to use in my programming of the back-end.

Windows is okay, if there are limited Mac FREE versions.

I do have Office 365 (Mac) if there is a tool in there which I can use.

I am also interested in hearing what "plug-ins" can work when I deploy this to my website, for online OCR conversions.

Security/Privacy related question.  Can text be detected in say a .jpg, . bmp, etc. type file formats?  I know using text within .pdfs can be with OCR.  When I say "detected" I mean with use of a SIEM, DLP or other event driven software?  Not referring to steganography or obfuscation of text in anyway.  Just simple text detection in a jpg or bmp format.  Much thanks.

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

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

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:

   OWNER PASSWORD REQUIRED, but not given (or incorrect)
Errors encountered.  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.

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?

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!
