Wavelet-based semi-automatic live-wire segmentation
Thomas Haenselmann, Wolfgang Effelsberg · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
The live-wire approach is a well-known algorithm based on a graph search to locate boundaries for image segmentation. We will extend the original cost function, which is solely based on finding strong edges, so that the approach can take a large variety of boundaries into account. The cost function adapts to the local characteristics of a boundary by analyzing a user-defined sample using a continuous wavelet decomposition. We will finally extend the approach into 3D in order to segment objects in volumetric data, e. g., from medical CT and MR scans.
