We propose an adaptive implementation of a Crouzeix–Raviart-based discretization of the total variation, which has the property of approximating from below the total variation, with metrication errors only depending on the local curvature, rather than on the orientation as is usual for other approaches.

简单网格总变化的Crouzeix–Raviart逼近

我们提出了一种基于Crouzeix-Raviart的总变化离散化的自适应实现方案，该离散化具有从总变化之下逼近的特性，度量误差仅取决于局部曲率，而不是其他方向通常的方向方法。
