title: OpenCV - Image Processing Technique for better reading of embossed characters (e.g in credit cards,plate number)
body: <p>So, I've already searched a lot of articles about image processing of plate numbers since it is basically just the same as reading embossed characters. But my problem is if the embossed characters color is the same as the color of the card it will be hard to recognize if I use Adaptive Threshold. Do you guys have any idea on how I will achieve my goal of reading embossed characters? Or if there's any article about it, it would be nice. Here's my sample image </p>
  
  <p>I've read this <a href="https://www.azoft.com/blog/ocr-embossed-text/" rel="nofollow noreferrer">article</a> but don't really know how to translate it into actual code.</p>
