text: In cortex surface segmentation, the extracted surface is required to have
a particular topology, namely, a two-sphere. We present a new method for removing
topology noise of a curve or surface within the level set framework, and thus
produce a cortical surface with correct topology. We define a new energy term
which quantifies topology noise. We then show how to minimize this term by computing
its functional derivative with respect to the level set function. This method
differs from existing methods in that it is inherently continuous and not digital;
and in the way that our energy directly relates to the topology of the underlying
curve or surface, versus existing knot-based measures which are related in a more
indirect fashion. The proposed flow is validated empirically.
