I want to take a circular region of interest from a rectangular image and project it onto a rectangle. This is illustrated in the following image:

I want to accomplish this, preferably using MATLAB, but even the general concept of how it can be done using any other language would suffice.

Thank you!

  • This is very similar to taking a fisheye lens image and undistorting it so that it maps to a rectangular plane. See this post for inspiration: http://stackoverflow.com/questions/2477774/correcting-fisheye-distortion-programmatically – rayryeng Mar 05 '15 at 07:27

    Thank you so much! I guess, I was just not searching with the right keywords :) – Srivatsan Ramasubramanian Mar 05 '15 at 07:58
  • No problem at all :) However, if you don't know the camera parameters of whatever device took that image, it's going to be a bit difficult to fully undistort the image properly. You'll have to play around with the parameters or do trial and error to get it working properly. Good luck! – rayryeng Mar 05 '15 at 08:23
