DynoSurf: Neural Deformation-based Temporally Consistent Dynamic Surface Reconstruction

no code implementations18 Mar 2024 Yuxin Yao, Siyu Ren, Junhui Hou, Zhi Deng, Juyong Zhang, Wenping Wang

Furthermore, we propose a learnable deformation representation based on the learnable control points and blending weights, which can deform the template surface non-rigidly while maintaining the consistency of the local shape.

Measuring the Discrepancy between 3D Geometric Models using Directional Distance Fields

no code implementations18 Jan 2024 Siyu Ren, Junhui Hou, Xiaodong Chen, Hongkai Xiong, Wenping Wang

We then transfer the discrepancy between two 3D geometric models as the discrepancy between their DDFs defined on an identical domain, naturally establishing model correspondence.

Unleash the Potential of 3D Point Cloud Modeling with A Calibrated Local Geometry-driven Distance Metric

1 code implementation1 Jun 2023 Siyu Ren, Junhui Hou

By associating each reference point with two given point clouds through computing its directional distances to them, the difference in directional distances of an identical reference point characterizes the geometric difference between a typical local region of the two point clouds.

GeoUDF: Surface Reconstruction from 3D Point Clouds via Geometry-guided Distance Representation

1 code implementation ICCV 2023 Siyu Ren, Junhui Hou, Xiaodong Chen, Ying He, Wenping Wang

We present a learning-based method, namely GeoUDF, to tackle the long-standing and challenging problem of reconstructing a discrete surface from a sparse point cloud. To be specific, we propose a geometry-guided learning method for UDF and its gradient estimation that explicitly formulates the unsigned distance of a query point as the learnable affine averaging of its distances to the tangent planes of neighboring points on the surface.

CorrI2P: Deep Image-to-Point Cloud Registration via Dense Correspondence

1 code implementation12 Jul 2022 Siyu Ren, Yiming Zeng, Junhui Hou, Xiaodong Chen

Motivated by the intuition that the critical step of localizing a 2D image in the corresponding 3D point cloud is establishing 2D-3D correspondence between them, we propose the first feature-based dense correspondence framework for addressing the image-to-point cloud registration problem, dubbed CorrI2P, which consists of three modules, i. e., feature embedding, symmetric overlapping region detection, and pose estimation through the established correspondence.

In this paper, we propose a novel configurable framework to automatically generate distractive choices for open-domain cloze-style multiple-choice questions, which incorporates a general-purpose knowledge base to effectively create a small distractor candidate set, and a feature-rich learning-to-rank model to select distractors that are both plausible and reliable.
