BARF: Bundle-Adjusting Neural Radiance Fields

4 code implementations ICCV 2021 Chen-Hsuan Lin, Wei-Chiu Ma, Antonio Torralba, Simon Lucey

In this paper, we propose Bundle-Adjusting Neural Radiance Fields (BARF) for training NeRF from imperfect (or even unknown) camera poses -- the joint problem of learning neural 3D representations and registering camera frames.

SDF-SRN: Learning Signed Distance 3D Object Reconstruction from Static Images

1 code implementation NeurIPS 2020 Chen-Hsuan Lin, Chaoyang Wang, Simon Lucey

Dense 3D object reconstruction from a single image has recently witnessed remarkable advances, but supervising neural networks with ground-truth 3D shapes is impractical due to the laborious process of creating paired image-shape datasets.

Deep NRSfM++: Towards Unsupervised 2D-3D Lifting in the Wild

1 code implementation27 Jan 2020 Chaoyang Wang, Chen-Hsuan Lin, Simon Lucey

The recovery of 3D shape and pose from 2D landmarks stemming from a large ensemble of images can be viewed as a non-rigid structure from motion (NRSfM) problem.

ST-GAN: Spatial Transformer Generative Adversarial Networks for Image Compositing

2 code implementations CVPR 2018 Chen-Hsuan Lin, Ersin Yumer, Oliver Wang, Eli Shechtman, Simon Lucey

We address the problem of finding realistic geometric corrections to a foreground object such that it appears natural when composited into a background image.

Semantic Photometric Bundle Adjustment on Natural Sequences

no code implementations30 Nov 2017 Rui Zhu, Chaoyang Wang, Chen-Hsuan Lin, Ziyan Wang, Simon Lucey

More recently, excellent results have been attained through the application of photometric bundle adjustment (PBA) methods -- which directly minimize the photometric error across frames.

Object-Centric Photometric Bundle Adjustment with Deep Shape Prior

no code implementations4 Nov 2017 Rui Zhu, Chaoyang Wang, Chen-Hsuan Lin, Ziyan Wang, Simon Lucey

Reconstructing 3D shapes from a sequence of images has long been a problem of interest in computer vision.


Using Locally Corresponding CAD Models for Dense 3D Reconstructions From a Single Image

no code implementations CVPR 2017 Chen Kong, Chen-Hsuan Lin, Simon Lucey

A common strategy in dictionary learning to encourage generalization is to allow for linear combinations of dictionary elements.

Learning Efficient Point Cloud Generation for Dense 3D Object Reconstruction

3 code implementations21 Jun 2017 Chen-Hsuan Lin, Chen Kong, Simon Lucey

Conventional methods of 3D object generative modeling learn volumetric predictions using deep networks with 3D convolutional operations, which are direct analogies to classical 2D ones.

The Conditional Lucas & Kanade Algorithm

1 code implementation29 Mar 2016 Chen-Hsuan Lin, Rui Zhu, Simon Lucey

In this paper, we present a new approach, referred to as the Conditional LK algorithm, which: (i) directly learns linear models that predict geometric displacement as a function of appearance, and (ii) employs a novel strategy for ensuring that the generative pixel independence assumption can still be taken advantage of.
