论文摘要
人体的3D可变形模型捕获受试者之间的变化，并且在重建和编辑应用中有用。当前的牙科模型使用明确的网格场景表示，仅模拟牙齿，忽略了口香糖。在这项工作中，我们介绍了牙齿和口香糖的第一个参数3D形态的牙科模型。我们的模型使用隐式场景表示形式，并且是从严格对齐的扫描中学到的。它基于每个牙齿和口香糖的组件表示，以及每个此类组件的可学习潜在代码。它还学习了模板形状，从而实现了几种应用，例如分割，插值和牙齿替换。我们的重建质量与最先进的全球隐式表示相等，同时可以实现新颖的应用。项目页面：https：//vcai.mpi-inf.mpg.de/projects/dmm/
3D Morphable models of the human body capture variations among subjects and are useful in reconstruction and editing applications. Current dental models use an explicit mesh scene representation and model only the teeth, ignoring the gum. In this work, we present the first parametric 3D morphable dental model for both teeth and gum. Our model uses an implicit scene representation and is learned from rigidly aligned scans. It is based on a component-wise representation for each tooth and the gum, together with a learnable latent code for each of such components. It also learns a template shape thus enabling several applications such as segmentation, interpolation, and tooth replacement. Our reconstruction quality is on par with the most advanced global implicit representations while enabling novel applications. Project page: https://vcai.mpi-inf.mpg.de/projects/DMM/
