myOCR

[peethebee]

Hi!

I coded a OCR script which is similar to one posted by someone before in order to read text in Diablo II (I think).

The important thing will be that in one of the next few versions an editor will make it possible to edit the character's data either manually or AUTOMATICALLY.

I would like you to test it and see the (I think impressive) screenshots.

Edit: The script can be grabbed in my fileman!

Wow... your script was able to read this text?

Are the characters alsways the same sign?

How much time does it take to read?

[peethebee]

Hi!

This text has been painted in MS Paint This is no special font. It compares a brunch of pixels where you can define if the pixel in relation to the starting pixel of the character HAs to be a special color or MUSN'T be of the color.

Look in the .ocr file to see the data (it's just a simple ini file)

Please ask your technical questions if there are more of them.

It takes about 2 sec I think on a 1.500 Ghz AMD Sempron with 256 MB RAM.

Cool...

Have to test it at home...

And be sure... I'll ask if there are coming questions

[peethebee]

I'm waiting for your results...

Thank you, w0uter!

Hi!

0.5 Beta inculdes a early (but working) version of the editor and a text file with tips how to speed up the scanning process.

Grab it via fileman.

Ah, yes I created the original D2 OCR

I actually ported it over to C#, it's about 100x faster.

EDIT:

I can't get yours to run correctly, I open up the image in paint and run both the exe and au3 file.

Hi!

100 times faster... not bad *g*.

You store the data similar to be, don't you?

Is there an editor aailible for your project?

Perhaps I could try to code one of not.

Deit: It should move the mouse to the start of the character. Perhaps try to use the other .ocr file as source, cause I played around very much with them.

Editor, oh no, that'd be very hard

Mine's specific and built for speed, not reusability. I store the data very differently, here's a snippit of the character definitions:

class OCRDefinition
{
    private Hashtable Definitions = new Hashtable();
    
    public OCRDefinition ()
    {
        // A-Z
        Definitions.Add ( "-1,0;-1,-1;-2,0;-2,-1;-8,0;-8,-1;", "A" );
        Definitions.Add ( "-1,0;-1,-1;-1,-2;-1,-3;-1,-4;-1,-5;-1,-6;-1,-7;-1,-8;-2,0;-2,-1;-2,-2;-2,-3;-2,-4;-2,-5;-2,-6;-2,-7;-2,-8;-3,0;-3,-3;-3,-7;-4,0;-4,-2;-4,-3;-4,-7;-5,0;-5,-1;-5,-2;-5,-3;-5,-4;-5,-5;-5,-6;-5,-7;", "B" );
        Definitions.Add ( "-1,0;-1,-1;-1,-2;-2,-1;-2,-2;-2,-3;-3,-3;-3,-4;-4,-4;-4,-5;-5,-4;-5,-5;-6,-4;-6,-5;-7,-4;", "C" );
        Definitions.Add ( "-1,0;-1,-1;-1,-2;-1,-5;-1,-6;-1,-7;-1,-8;-2,0;-2,-1;-2,-2;-2,-3;-2,-4;-2,-5;-2,-6;-2,-7;-2,-8;-4,0;-4,-7;-5,0;-5,-7;-6,0;-6,-1;-6,-6;-6,-7;-7,-1;-7,-2;-7,-3;-7,-4;-7,-5;-7,-6;", "D" );

Hi!

ok. I will stay with my project *g*.

But I think you also store a set of coordinates of the pixels, don't you?

Edit: Does the scanning work now?

I got it to work, sorry I went to eat a snack. I forget completely what I did to change it. I think I used a different picture (the ABC.. one)

I do not set a coordinate of the pixels? The "0,1;0,2;" are the distances of the pixels from the top left most part of the character.

[peethebee]

I do the same thing (relative coordinates = distances).

peethebee

[Insolence]

Yes but you also save the pixels, and you have a seperate definition for each pixel of a character, whereas I only have 1 definition for an entire character.

Hi!

This is a feature for chars which are not mono-colored.

I just read the forum thread about plugins in C/C++.

As you seem to be a skilled C# coder I would suggest that we (or you) could write a plugin to scan a part of the screen. It could be almost as fast as your solution and at the same time as open for other fonts as my way to implement it.

If you do not want to help me I would like to see your C# code as I justz started to code C++.

Thank you, peethebee

You can get the entire project here: http://insolence9.com/downloads/RealOCR.zip

You'll need SharpDevelop (www.icsharpcode.com I think)

If I linked to the wrong archive, let me know

[peethebee]

Hi!

Thanks for sharing the source. I got it to run, but it showed many MsgBoxes so that I have to remove them in order to see, if the scanning works.

Yeah, I had to do a lot of debugging in that sense, sorry
