CityDreamer: Compositional Generative Model of Unbounded 3D Cities

no code implementations1 Sep 2023 Haozhe Xie, Zhaoxi Chen, Fangzhou Hong, Ziwei Liu

In recent years, extensive research has focused on 3D natural scene generation, but the domain of 3D city generation has not received as much exploration.

Spatio-Temporal Deformable Attention Network for Video Deblurring

1 code implementation22 Jul 2022 Huicong Zhang, Haozhe Xie, Hongxun Yao

The key success factor of the video deblurring methods is to compensate for the blurry pixels of the mid-frame with the sharp pixels of the adjacent video frames.

Long-Range Feature Propagating for Natural Image Matting

1 code implementation25 Sep 2021 Qinglin Liu, Haozhe Xie, Shengping Zhang, Bineng Zhong, Rongrong Ji

Finally, we use the matting module which takes the image, trimap and context features to estimate the alpha matte.

Pix2Vox++: Multi-scale Context-aware 3D Object Reconstruction from Single and Multiple Images

3 code implementations22 Jun 2020 Haozhe Xie, Hongxun Yao, Shengping Zhang, Shangchen Zhou, Wenxiu Sun

A multi-scale context-aware fusion module is then introduced to adaptively select high-quality reconstructions for different parts from all coarse 3D volumes to obtain a fused 3D volume.

GRNet: Gridding Residual Network for Dense Point Cloud Completion

1 code implementation ECCV 2020 Haozhe Xie, Hongxun Yao, Shangchen Zhou, Jiageng Mao, Shengping Zhang, Wenxiu Sun

In particular, we devise two novel differentiable layers, named Gridding and Gridding Reverse, to convert between point clouds and 3D grids without losing structural information.

Single-View 3D Object Reconstruction from Shape Priors in Memory

no code implementations CVPR 2021 Shuo Yang, Min Xu, Haozhe Xie, Stuart Perry, Jiahao Xia

Inspired by this, we propose a novel method, named Mem3D, that explicitly constructs shape priors to supplement the missing information in the image.

Toward 3D Object Reconstruction from Stereo Images

1 code implementation18 Oct 2019 Haozhe Xie, Hongxun Yao, Shangchen Zhou, Shengping Zhang, Xiaoshuai Sun, Wenxiu Sun

Inferring the 3D shape of an object from an RGB image has shown impressive results, however, existing methods rely primarily on recognizing the most similar 3D model from the training set to solve the problem.

Spatio-Temporal Filter Adaptive Network for Video Deblurring

1 code implementation ICCV 2019 Shangchen Zhou, Jiawei Zhang, Jinshan Pan, Haozhe Xie, WangMeng Zuo, Jimmy Ren

To overcome the limitation of separate optical flow estimation, we propose a Spatio-Temporal Filter Adaptive Network (STFAN) for the alignment and deblurring in a unified framework.

Pix2Vox: Context-aware 3D Reconstruction from Single and Multi-view Images

5 code implementations ICCV 2019 Haozhe Xie, Hongxun Yao, Xiaoshuai Sun, Shangchen Zhou, Shengping Zhang

Then, a context-aware fusion module is introduced to adaptively select high-quality reconstructions for each part (e. g., table legs) from different coarse 3D volumes to obtain a fused 3D volume.
