提出了一种基于L-0最小化的三角模型去噪算法。我们的方法最大化了模型的平坦区域,并在保留尖锐特征的同时逐渐去除了噪声。作为这一过程的一部分,我们为任意三角形网格构建了一个离散微分算子,该算子对于退化三角剖分是健壮的。我们将我们的方法与其他各向异性去噪算法进行了比较,结果表明,即使在高噪声的情况下,我们的方法也具有更好的鲁棒性和良好的去噪效果。
We present an algorithm for denoising triangulated models based on L-0 minimization. Our method maximizes the flat regions of the model and gradually removes noise while preserving sharp features. As part of this process, we build a discrete differential operator for arbitrary triangle meshes that is robust with respect to degenerate triangulations. We compare our method versus other anisotropic denoising algorithms and demonstrate that our method is more robust and produces good results even in the presence of high noise.
