title: Image Manipulation: Convert embossed letters to normal letters
body: <p>I'm searching for a way to convert embossed letters e.g. like in the picture of the credit card below to normal ones like you see them in a book. I don't need specific code here, just ideas which image manipulation steps could lead to the desired result. </p>
