[RELEASE] OCR - Tesseract trainedata for attackspeed

[Interløgy]

Hello,

Here is a small release for people who want to make an external lol script.

SpaceGlider uses a screenshot to read the attack speed.
A machine can not read out numbers from a picture. Therefore Tesseract was used, because this is probably the best open source OCR.

The advantage of the training data of SpaceGlider is:
- Size of the HUD doesn't matter
- Very high accuracy
- Much faster (about 60 ms faster)


I initialized it like this:

instance = new Tesseract();
instance.setTessVariable("user_defined_dpi", "1000");
instance.setTessVariable("tessedit_char_whitelist", "0123456789.");
instance.setDatapath("./tessdata");
instance.setLanguage("LoL");

Meanwhile there is an API to read out the attack speed.
But nobody knows if it will stay forever, because this API is quite abused.

Credits to trickory#0616, who trained the font for Tesseract. <3

How to use?

Using tesseract alone in your script will be very slow as it requires many steps to be taken for each iteration. Especially when you have a potato pc.

I would recommend it for experimental use only.

It's a language file designed for the league of legends font style.

It's a language file designed for the league of legends font style.

It takes 10ms to 15ms to read out the attack speed (Instead of 60-100ms)
So it could be used for attackspeed easy without Autoattack-Cancel.

Which programming language you´re using?
Just look for a tutorial how to use Tesseract.

When initializing the instance of Tesseract, you must specify my trainedata.

I initialized it like this:

instance = new Tesseract();
instance.setTessVariable("user_defined_dpi", "1000");
instance.setTessVariable("tessedit_char_whitelist", "0123456789.");
instance.setDatapath("./tessdata");
instance.setLanguage("LoL");

I've also prepared the picture a bit:
(May you should not overwrite the parameter like i did)

public BufferedImage improveQuality(BufferedImage subimage) {
    subimage = ImageHelper.convertImageToGrayscale(subimage);
    subimage = ImageHelper.invertImageColor(subimage);
    subimage = ImageHelper.getScaledInstance(subimage, subimage.getWidth() * 3, subimage.getHeight() * 3);
    return subimage;
}

Nice release!
Thank you for this ^^

but How can that helps with the attack cast time ?

Interesting, thanks will be useful to play around with.

If you make an external Orbwalker, this file will help you to make your tesseract more accurate and faster.
