Abstract

Aim: To develop a method for automatic contour extraction from a 2D image. Material and Method:The method is divided in two basic parts where the user initially chooses the starting point and thethreshold. Finally the method is applied to computed tomography of bone images. Results: Aninteresting method is developed which can lead to a successful boundary extraction of 2D images.Specifically data extracted from a computed tomography images can be used for 3D bone reconstruction. Conclusions: We believe that such an algorithm or part of it can be applied on severalother applications for shape feature extraction in medical image analysis and generally at computergraphics.
