在本文中，我们提出了一种新的配准辅助图像分割问题的变分制剂，导致解决一组耦合的非线性偏微分方程，解决了使用高效的数值方案。我们的工作是从早期的方法出发，我们有一个统一的变分原理，其中非刚性注册和分割同时实现，与以前的方法解决这个问题，我们的算法可以适应图像对具有非常不同的强度分布。我们提出的例子，我们的算法上的合成和真实的数据集沿着与定量精度估计的注册性能。
In this paper, we present a novel variational formulation of the registration assisted image segmentation problem which leads to solving a coupled set of nonlinear PDEs that are solved using efficient numerical schemes. Our work is a departure from earlier methods in that we have a unified variational principle wherein non-rigid registration and segmentation are simultaneously achieved; unlike previous methods of solution for this problem, our algorithm can accommodate for image pairs having very distinct intensity distributions. We present examples of performance of our algorithm on synthetic and real data sets along with quantitative accuracy estimates of the registration.
