title = "Elastic image registration using linear basis functions for non-continuously deforming objects",
abstract = "In the current study we propose an elastic image registration algorithm for a non-continuous motion field and spatially varying properties of the domain. The approach is based on using linear basis functions that inherently have non-continuous derivatives and allow geometric separation of an object from its background. We use the elastic regular-ization term commonly used in finite element analysis and combine it with the recent state-of-the-art image registration optimization method. We validated our algorithm's concept using simulation of a non-continuous motion field obtained by hand articulations and tested the effect of the object's background on the algorithm's convergence. We show that for non-continuously deforming objects the proposed algorithm outperforms commonly used registration algorithms that work on a regular grid of control points.",
