var tesseract = require('node-tesseract');

      tesseract.process('17.jpg', (err, text) => {
        if(err){
            return console.log("An error occured: ", err);
        }

        console.log("Recognized text:");
        // the text variable contains the recognized text
        console.log(text);


        /*

Try '--psm' instead of '-psm'.
