Compress3D: a Compressed Latent Space for 3D Generation from a Single Image

no code implementations20 Mar 2024 BoWen Zhang, Tianyu Yang, Yu Li, Lei Zhang, Xi Zhao

In this paper, we present a triplane autoencoder, which encodes 3D models into a compact triplane latent space to effectively compress both the 3D geometry and texture information.

Reconstructing 3D Human Pose from RGB-D Data with Occlusions

no code implementations2 Oct 2023 Bowen Dang, Xi Zhao, BoWen Zhang, He Wang

Our key idea is to constrain the solution space of the human body by considering the occluded body parts and visible body parts separately: modeling all plausible poses where the occluded body parts do not penetrate the scene, and constraining the visible body parts using depth data.

CBNet: A Plug-and-Play Network for Segmentation-Based Scene Text Detection

1 code implementation5 Dec 2022 Xi Zhao, Wei Feng, Zheng Zhang, Jingjing Lv, Xin Zhu, Zhangang Lin, Jinghe Hu, Jingping Shao

Recently, segmentation-based methods are quite popular in scene text detection, which mainly contain two steps: text kernel segmentation and expansion.

Shape Completion with Points in the Shadow

1 code implementation17 Sep 2022 BoWen Zhang, Xi Zhao, He Wang, Ruizhen Hu

The core challenge is to generate plausible geometries to fill the unobserved part of the object based on a partial scan, which is under-constrained and suffers from a huge solution space.

A Learned Index for Exact Similarity Search in Metric Spaces

no code implementations21 Apr 2022 Yao Tian, Tingyun Yan, Xi Zhao, Kai Huang, Xiaofang Zhou

In this paper, we propose a novel indexing approach called LIMS that uses data clustering, pivot-based data transformation techniques and learned indexes to support efficient similarity query processing in metric spaces.

Informative Scene Decomposition for Crowd Analysis, Comparison and Simulation Guidance

no code implementations29 Apr 2020 Feixiang He, Yuanhang Xiang, Xi Zhao, He Wang

The method takes as input raw and noisy data with highly mixed multi-dimensional (space, time and dynamics) information, and automatically structure it by learning the correlations among these dimensions.

City Metro Network Expansion with Reinforcement Learning

no code implementations25 Sep 2019 Yu Wei, Minjia Mao, Xi Zhao, Jianhua Zou

In this method, we formulate the metro expansion as a process of sequential station selection, and design feasibility rules based on the selected station sequence to ensure the reasonable connection patterns of metro line.

Retrieving Similar Trajectories from Cellular Data at City Scale

no code implementations20 Jul 2019 Zhihao Shen, Wan Du, Xi Zhao, Jianhua Zou

Retrieving similar trajectories from a large trajectory dataset is important for a variety of applications, like transportation planning and mobility analysis.

Improving Shadow Suppression for Illumination Robust Face Recognition

no code implementations13 Oct 2017 Wuming Zhang, Xi Zhao, Jean-Marie Morvan, Liming Chen

2D face analysis techniques, such as face landmarking, face recognition and face verification, are reasonably dependent on illumination conditions which are usually uncontrolled and unpredictable in the real world.
