I am creating an anatomical atlas of CTs and have a student laboriously
identifying anatomical points with a mouse click. I would like to use a
pair of x,y cords as a starting point to automatically search for a
region which has similar properties in terms of grayness which will
outline the anatomical structure such as the Maxillary sinus. Is there a
macro which if you give it a starting x,y coordinate will search around
to form a closed ROI?

 

Thanks!
