In this letter, we propose a robust, linear in time modification of Aktouf, Bertrand and Perroton's algorithm for tunnel (3D hole) closing in 3D volumetric objects. Our algorithm is insensitive to small distortions and branches. The algorithm has been tested on various 3D images including very complicated 3D crack propagation images. The results of the tests, discussion of the algorithm properties and future research plans are also included in the paper. (C) 2011 Elsevier B.V. All rights reserved.
