The numbers are outlined, the lines are the same color as the letters, and there's a good amount of distortion. This one won't be easy to solve with the tools I've included in this library.

You could maybe try binarizing the image, flood filling the background black (so the numbers become solid white), and then doing a vertical blur to hopefully remove the lines. Good luck.

Thank you very much. I will give it a try. Great library!
