I'm looking for simple techniques to segment out the optical disk and vessels from a retinography. By simple I mean using techniques taught during an introductory course on Digital Image Processing.

I looked for papers on the subject but all of them included more advanced or complicated techniques.

Do you have any suggestions?

It doesn't need to achieve a very high accuracy of segmentation and it doesn't need to be extremely robust.


  • $\begingroup$ My slight problem with your question is that I don't know the entry-level image processing course you're thinking about -- which sadly puts exactly you in the best position to answer your own question. Maybe you'd want to illustrate by explaining a few approaches that have crossed your mind so far! $\endgroup$ – Marcus Müller May 31 '17 at 7:12
  • $\begingroup$ By "entry-level" I mean anything in the Gonzalez and Woods book for example. I've tried thresholding the green channel to segment out the optic disk (the brighter section). The result is not good, whether you segment too much or too little around the optic disk. I'm experimenting right now with the vessels. I posted the question because by looking the papers on the subject it seemed like a very difficult task. $\endgroup$ – Esteban Filardi May 31 '17 at 13:20
