Sir please correct me if I am wrong
So there are three main obstacles that we have to achieve.
1. Identifying the objects (Either polygons or NURBS) separately instead of
going into pixels of the image space
2. Mapping the objects with their corresponding location. (I think I don't
get this clearly though)
3. Using the location constructing splines (or 2d curves) for each
identified objects. and that is the vector representation of each objects
that we have identified.
this is what I got from the project description and your mail.
Thank You
