So I have a bunch of data on an image that is condensed into an outer ring around a picture.

It looks something like this.

image description

What I want to do is take the segmented circle and unwrap it so it's a segmented line.

If you know the center, you can use the linearPolar function to unwrap the image. You use the WARP_INVERSE_MAP to make it go from polar to cartesian, and now it's a line.

I'm not sure what point would be the beginning of the line, but you can experiment.
