Using OCR As Text Recognition?
Apr 15, 2012
i'm trying to build a form which can extract a text from a picture(jpeg). Let say that i have 1 picture which contain text "TE66" on it. Then i browse for it,put it in ad picturebox and after that,i need to click a "capture" button to extract the text "TE66" and show it on textbox.
i already search about this on the internet but unfortunately, i cant find one. what i know is to extract a text from a picture is we need a Microsoft Office Document Imaging Visual Basic Reference (MODI). i already installed one but i dont know where to start first.

I am trying to read text from an image. I have been trying to use OCR from MODI but I keep getting an error. Here is the simplest version of code (I've tried several)
Dim miDoc As MODI.Document
miDoc = New MODI.Document
miDoc.Create("C:document1.bmp")
miDoc.OCR()
miDoc = Nothing
As far as I can tell, my program gets stuck every time it gets to:
miDoc = New MODI.Document
it tells me a COMException was unhandled
I am using vb in vb.net, and I have a reference to the COM "Microsoft Office Document Imaging 12.0 Type Library". Every thing I have tried seems to come up with the same error.

I'm trying to create a Speech Recognition support for my program. I want to make it so that if I say something in my microphone, the program just writes what I said in Label1. I looked for Speech Recognition codes in MSDN and Google, but I didn't find anything useful. I found a code, but it was for VB.net, I tried but it didn't work in VB 2010.

I am trying to write a 'simple' program with vs 2005 that recognises my specific usb memory stick so that I can make windows log off or 'lock' when the device is not in any slot. I have found some ready code and I am trying to modify it for my needs. There compiling works but when it doesnt find any of the usb ports.It works by checking each port if it is a usb port and then compares the vendor and produck ID to the given. it seems simple enough but I cant get it to find the USB.
Here is the code:

I'm working on a program that needs Speech Recognition and every website says to download the Microsoft Speech Recognition Engine. I can't find that, but I've downloaded all the SDKs. Are they the same? And it always says to add a speech recognition component to the form, but I can't find where that is in Visual Basic 2005. I'm using the Express Edition, but I don't think that matters.

what I gather, the biggest difference between the old SAPI 5.1 and SAPI 5.3 is that SAPI 5.3 actually takes less code to do some of the same things that SAPI 5.1 does. This is just a simple example that runs notepad and says it is before doing so.One thing to remember is that the name of speech lib is changed again. Now you have to do this: Project -> Add Reference -> .NET -> System.Speech
imports system.speech
Public Class Form1
Public WithEvents recognizer As New System.Speech.Recognition.SpeechRecognitionEngine
Dim gram As New System.Speech.Recognition.DictationGrammar()
[code]....
gram is a DictationGrammar object. As it turns out, there are two grammar objects in SAPI 5.3. As you've probably already guessed, DictationGrammar is for spoken language and the normal grammar object is for simple grammar rules.
So basically, Load the grammar, set audio to the default input device and then start an Async recognize call. They have a blocking recognize call and one thing to note here is that it will turn itself off after each sucessful recognized phrase. Meaning that you have to recall Async recognize at the end of the GotSpeech sub if you want to keep picking up voice commands. As it stands, this will pick up one command and no more because it stops recognition.
One neat thing about the synthesis engine is that you can specify things like ".NET" to be said as "dot net" by Anna. Also, as it stands, the periods aren't said and so are pretty much useless. It acts just like the Vista Recognition engine also so if you spell out a word, Anna will spell it out too.In this example there is an undeclared variable named "cmd" that I fail to understand. What is the role of it and where does it obtain it's value from. I actually assume it should be the one to get the decoded\recognized text from the recognizer but not sure how that is achieved.

i would like to know on how to recognize a written character using vb.net 2008. it's actual a simple drawing using paint or system.windows.drawing. i've been googling for days but i didnt find anything related tothe image that i had attach below.hat i need to used.based on my understanding, by defaults the "dot" value is zero.whenever the user write each connected "dot", it will give 1 value. itssimply binary code.let say. 1001101100 = b

I was recently pursuing code that would allow me to read machine text off an image. The text will only consist of characters a-b, 0-9 and a few special characters (+,=,-,@,&). I have pursued a few third party OCR controls however all require licenses to be fully functional, would anyone know of any third party OCR controls that does not cost anything? If not is there anyway i can build my own OCR control that will read machine text?

I'm using Speech.Recognition.SpeechRecognizer in VB.NET 2010 on XP-SP3. I can't figure out how to get it to recognize a number as a number. I want to be able to say "five" and have the code interpret it as the value 5 instead of the word. I know I could use a long choices array or sementics key/value combintations as I have for other conditions but that would be a considerable amount of hard coding or XML work. Is there a more efficient way to get the desired result?

I'm making an application that requires me to perform speech recognition from a wave file that contains some speech. I know what the words in the wave file could be.So, I need to compare these words from a small custom grammar/dictionalr instead of a whole built in large vocabulary.
I have done the recognition part with the default system large vocabulary but now just need to use my own vocabulary.
Suppose that the words that the user can say are:
Hello
hundred degree celcius,
USA,
Yes,
No
Then, how shall I write my XML Grammar? I suppose that if I use the limited small vocabulary, then my accuracy of recognition would increase. Right now, ive a wave file in Microsoft Mary's voice saying "Hello". But with the large default vocabulary its recognising it as "All though". Is my assumption correct that with the above mentioned 5 words in the vocabulry, it will recognise it as Hello only?
Ive been looking at the internet but can't find solution to my specific problem regarding making a simple grammar. In most documents its mentioning using external grammar and about several of the attributes posssible, including sementics, etc, etc. But my vocabulary is not very complicated or difficult. And I don't want to get into too much detail at the moment as I would be deviating from my project itself..
So using the following code:
Grammar = RecoContext.CreateGrammar
Grammar.CmdLoadFromFile("C:CustomGrammar.xml")
What should be the content of the CustomGrammar.xml?

I am really new to all of this, and especially new to VB 2008, so while searching around for how to use Speech Recognition in VB, i figured i would ask here to get the best solution. I know that it is rather complicated, but my program only needs to understand maybe 20 commands max. So if anyone could post help on where i even need to get started to start speech recognition in my program,

All of the examples I'm finding on the internet are 5 or 6 years old or they are text-to-speech and I need speech input capability. I have a form that I would like to be enterable by voice.One of the textboxes on the form is for a description so I need something that will understand the spoken English language as well as possible.

I was wondering if it was possible to create a program in vb that recognizes a window/form and performs certain actions based on that. Basically what I want to do is create a program that auto fills out and clicks buttons on an install wizard to automatically install a program. I guess like some what of a macro. NOTE: I will only be using this only one installer, since I have to install this program multiple times.

I recently started a project and I have successfully completed the autoclicker part. But I am wondering how to add on to the autoclicker to make it locates a color and then click on that color. So for example:
User presses find color button (color the mouse is currently over)
Cursor finds color red,
Cursor locates and clicks all color reds until new color is clicked,
Repeat.

So, you've all probably seen Iron Man where Tony interacts with an AI system called Jarvis. Demo clip here (Sorry it's a commercial).I'm very familiar with C#, C++ and Visual Basic, but I am unsure what options I have available for me to program something like this. Ideally, I'd like to have it assist me while working on some projects by automating a few things.
After doing a bit of research, I saw that a lot of people where using apple script. Well, I'm a windows developer and I work on windows, SO, that won't work.Microsoft has a Speech SDK, but I hear that I can't program it to learn custom words... as in it just uses it's standard library. Is this true? What are the other limitations of speech recognition with the SDK? Is there something else then?
Also, which language would be better to use for a project like this? C# or VB?

I've written a "quick and dirty" GUI interface for a CLI chat program, and I've been trying to integrate TTS and Speech Recognition into it, so that the user can "have a conversation" with a chat bot, rather than just "type and read". The TTS portion works well (barring some small pronunciation issues - I have yet to find a TTS voice that can properly pronounce "Geek" without my having to mangle the spelling), and the SR module works well.
If I have the TTS module disabled. The problem I'm having is that the SR module is processing the output from the TTS, and causing issues where an ever-increasing string of TTS output occurs, causing undesirable results. I've tried several methods of temporarily disabling Speech recognition, none of which have proved useful. Below are some short code snippets that I've tried to use:
Imports SpeechLib
Imports System.Drawing
Imports System.Net.Sockets
Public Class Form1
Public voice As New SpVoice
