[select and unroll circular patch border]

Hi All;

Paint looks powerful - I'm a n00b with a question for someone who knows how-

I want to read the text from a scanned image of a soviet/russian? military patch.

I collect patches that have maps. Bought this one at a street fair in Anchorage but can't read it.

So I am looking for a way to isolate the border and change it from a circle to a straight line.

Then I can feed the result image into an image ocr to text and translate application.

is this possible?

thanks for your time,

Holly
