Hi Firas, I send you a section of my master's thesis which contains the information you need. To make it short, it is O(n^2) for a three dimensional image. It was to big to attach so find the file here: http://dl.dropbox.com/u/9419356/levelset.png If you need more information, please let me kn

Hi Luca and the others, assuming we have a 3D volume of size n^3 , is there a complexity term and memeroy requirement term for levelsetsegmentation. As levelsetsegmentation is evolving an embedding function in time, is the complexity something like O(m*n^3) where m is the number of iterations? wit
