Extraction of Connected Region Boundary in Multidimensional Images

International audienceThis paper presents an algorithm to extract the boundary of a connected region(s) using classical topology definitions. From a given adjacency definition, the proposed method is able to extract the boundary of an object in a generic way, independently of the dimension of the digital space. Source Code The implementation of the algorithm is available through the DGtal library 1 . The source code and the demonstration are based on a special version of DGTal containing no external dependencies. They are both available on the IPOL web page of this article 2 . Supplementary Material The DGtalTools 3 project gives several additional tools exploiting the proposed algorithms. These tools are defined to process both 2D and 3D images
