MVDiffusion++: A Dense High-resolution Multi-view Diffusion Model for Single or Sparse-view 3D Object Reconstruction

no code implementations20 Feb 2024 Shitao Tang, Jiacheng Chen, Dilin Wang, Chengzhou Tang, Fuyang Zhang, Yuchen Fan, Vikas Chandra, Yasutaka Furukawa, Rakesh Ranjan

MVDiffusion++ achieves superior flexibility and scalability with two surprisingly simple ideas: 1) A ``pose-free architecture'' where standard self-attention among 2D latent features learns 3D consistency across an arbitrary number of conditional and generation views without explicitly using camera pose information; and 2) A ``view dropout strategy'' that discards a substantial number of output views during training, which reduces the training-time memory footprint and enables dense and high-resolution view synthesis at test time.

Learning To Zoom Inside Camera Imaging Pipeline

no code implementations CVPR 2022 Chengzhou Tang, Yuqiang Yang, Bing Zeng, Ping Tan, Shuaicheng Liu

To these ends, we design a method that receives a low-resolution RAW as the input and estimates the desired higher-resolution RAW jointly with the degradation model.

Learning Camera Localization via Dense Scene Matching

1 code implementation CVPR 2021 Shitao Tang, Chengzhou Tang, Rui Huang, Siyu Zhu, Ping Tan

We present a new method for scene agnostic camera localization using dense scene matching (DSM), where a cost volume is constructed between a query image and a scene.

DRO: Deep Recurrent Optimizer for Video to Depth

1 code implementation24 Mar 2021 Xiaodong Gu, Weihao Yuan, Zuozhuo Dai, Siyu Zhu, Chengzhou Tang, Zilong Dong, Ping Tan

There are increasing interests of studying the video-to-depth (V2D) problem with machine learning techniques.

BA-Net: Dense Bundle Adjustment Networks

no code implementations ICLR 2019 Chengzhou Tang, Ping Tan

The network first generates several basis depth maps according to the input image, and optimizes the final depth as a linear combination of these basis depth maps via feature-metric BA.

Linear Global Translation Estimation with Feature Tracks

no code implementations6 Mar 2015 Zhaopeng Cui, Nianjuan Jiang, Chengzhou Tang, Ping Tan

This paper derives a novel linear position constraint for cameras seeing a common scene point, which leads to a direct linear method for global camera translation estimation.
