Abstract

The polygon mesh representation of 3D data exhibits great flexibility, fast rendering speed, and storage efficiency, which is widely preferred in various applications. However, given its unstructured graph representation, the direct generation of high-fidelity 3D meshes is challenging. Fortunately, with a pre-defined ordering strategy, 3D meshes can be represented as sequences, and the generation process can be seamlessly treated as an auto-regressive problem. In this paper, we validate the Neural Coordinate Field (NeurCF), an explicit coordinate representation with implicit neural embeddings, is a simple-yet-effective representation for large-scale sequential mesh modeling. After that, we present MeshXL, a family of generative pre-trained auto-regressive models, which addresses the process of 3D mesh generation with modern large language model approaches. Extensive experiments show that MeshXL is able to generate high-quality 3D meshes, and can also serve as foundation models for various down-stream applications.

Abstract

In this paper, we investigate the $L^{p}$ coarse Baum-Connes conjecture for $p\in [1,\infty)$ via $C_{0}$ coarse structure, which is a refinement of the bounded coarse structure on a metric space. We prove the $C_{0}$ version of the $L^{p}$ coarse Baum-Connes conjecture and thus construct an obstruction group for the conjecture. As an application, we show that the obstructions vanish under the assumption of finite asymptotic dimension, and hence give a new proof of the $L^{p}$ coarse Baum-Connes conjecture in this case., Comment: 29 pages

Abstract

Objective To evaluate and compare the impact of three root canal sealers (C-Root SP, iRoot SP, and AH-Plus Jet) on the sealing performance in single-cone root canal filling using micro-computed tomography (Micro-CT). Methods Ninety mandibular single-rooted extracted teeth meeting inclusion criteria were collected, prepared with Protaper Next up to X3, and randomly assigned to three experimental groups which were C-Root SP group (Group A), iRoot SP group (Group B), and AH-Plus Jet group (Group C). Subsequently, all three groups underwent single-cone root canal filling, followed by one week of oral environment simulation. The sealing performance of the three root canal sealers was evaluated by measuring the proportion of the root canal volume and its rate using Micro-CT. Results In different segments of the roots (upper 1/3, middle, and lower), identifiable bubbles were observed in the Group A, Group B and Group C, with volumes of (0.15±0.03)mm3, (0.22±0.11)mm3, and (0.34±0.28) mm3, respectively. Overall, Group A exhibited the smallest bubble volume (0.15±0.03) mm3. Group A and B were similar, they were superior to group C. (P

Abstract

In this paper, we study the persistence approximation property for quantitative $K$-theory of filtered $L^p$ operator algebras. Moreover, we define quantitative assembly maps for $L^p$ operator algebras when $p\in [1,\infty)$. Finally, in the case of $L^{p}$ crossed products and $L^{p}$ Roe algebras, we find sufficient conditions for the persistence approximation property. This allows us to give some applications involving the $L^{p}$ (coarse) Baum-Connes conjecture., Comment: 33 pages, to appear in Chinese Ann. Math. Ser. B

Abstract

In this paper, we present a large-scale detailed 3D face dataset, FaceScape, and the corresponding benchmark to evaluate single-view facial 3D reconstruction. By training on FaceScape data, a novel algorithm is proposed to predict elaborate riggable 3D face models from a single image input. FaceScape dataset releases $16,940$ textured 3D faces, captured from $847$ subjects and each with $20$ specific expressions. The 3D models contain the pore-level facial geometry that is also processed to be topologically uniform. These fine 3D facial models can be represented as a 3D morphable model for coarse shapes and displacement maps for detailed geometry. Taking advantage of the large-scale and high-accuracy dataset, a novel algorithm is further proposed to learn the expression-specific dynamic details using a deep neural network. The learned relationship serves as the foundation of our 3D face prediction system from a single image input. Different from most previous methods, our predicted 3D models are riggable with highly detailed geometry under different expressions. We also use FaceScape data to generate the in-the-wild and in-the-lab benchmark to evaluate recent methods of single-view face reconstruction. The accuracy is reported and analyzed on the dimensions of camera pose and focal length, which provides a faithful and comprehensive evaluation and reveals new challenges. The unprecedented dataset, benchmark, and code have been released at https://github.com/zhuhao-nju/facescape., Comment: Accepted to T-PAMI 2023; Extension of FaceScape(CVPR 2020); Code & data are available at https://github.com/zhuhao-nju/facescape
