Read text from image

[XverhelstX]

Hello,

Is there a way to read text from a picture you have taken?

Sub Camera1_PictureTaken (Data() As Byte)
   camera1.StartPreview
   out = File.OpenOutput(File.DirRootExternal, "Example.jpg", False)
   out.WriteBytes(data, 0, data.Length)
   
   readLength = data.Length
   readData = BConverter.CharsFromBytes(Data)
   
   ToastMessageShow("Image saved: " & File.Combine(File.DirRootExternal, "Examplek.jpg"), True)
   btnTakePicture.Enabled = True
End Sub

Sub btnTakePicture_Click
   btnTakePicture.Enabled = False
   camera1.TakePicture
End Sub

Sub btnReadPicture_Click
   
   Dim Reader As TextReader
    Reader.Initialize(File.OpenInput(File.DirRootExternal, "Example.jpg"))
    Dim line As Int
    line = Reader.Readall
   Msgbox(line,"")
   out.Close

End Sub

This is my try, but I don't know how to work on this further.
any help? :sign0163:

I guess you will need some kind of OCR library for that.

Thanks NJDude,

is there also another way?

and can someone (agraham ) take a look at this (attachments), and see if it works?

I modified it a bit to work with B4A.

Can anyone take a look at this library please?
I edited it a bit to make it work with Basic4android, but I still have some problems.

It has a scanner, Trainingimages and more

There is nothing to "look at". No source, no demo program demonstrating a problem, no training character image files - just a jar and an xml with almost no comments in it but using PixelImage and CharacterRange types that don't seem to be exposed to B4A!

Ugh

I have played with Ron's OCR engine before and it is useless with photos. Works somewhat OK with text on pure white plus you have to train it for each image you want to process. I too am looking for a decent OCR solution.

Oh, ok, altough it would be really much appreciated if someone could make/edit an OCR Library.
I might have find another way to do it, but I guess it will be expensive.

Expense is not the problem, the issue is the effectiveness of the app or library.

I've dealt in the past with OCR apps and they are a royal pain in the neck, now you want to read text off a picture, well, good luck with that, unless the text is on a high contrast area and at a certain angle (and in some instances the right color) you might be able to get a letter or 2.

Just my 2 cents.

 

[XverhelstX]

Hmm thanks for this info, NJDude.
Didn't know OCR was that complicated.

thanks anyway,

Really good job. Did you finally release it?
