Javascript – Ocrad / Ocr – how to extract numerical images exactly


Thanks in advancePicture of my problem

I have to return Ocrad more exact numeric values.

I did the following:
I created a loop with a series of images.
After that, I created a function like this:

< script src="https://pt.stackoverflow.com/ocrad.js">< / script>







detect_image () {

document.getElementById (& # 39; transcription & # 39;). innerText = "(recognize ...)"

OCRAD (document.getElementById ("pic"), {// take a picture
numeric: define true // as numeric
}, Function (text) {// returns text


document.getElementById (& # 39; transcription & # 39;). className = "done"
document.getElementById (& # 39; transcription & # 39;). innerText = text;
})
} 

js is a bridge for my ocrad lib 0.25;
How do I return more accurate values?
my pictures are in png with white background.

and how to change the reading or comparison model What uses Ocrad to increase accuracy?
since I will only use this type of images with this source:
