摘要
This work is a contribution to the problem of detection of thin structures, namely tubes, in a 2 D or 3 D image. We introduce a variational bimodal model for the case where the histogram of the image has two main modes. This model involves an energy functional that depends on a function and a Riemannian metric. One of the terms of this energy is the anisotropic perimeter associated to the dual metric. We perform an approximation of this functional and prove that it Gamma-converges to the original one.
