ZipLoRA: Any Subject in Any Style by Effectively Merging LoRAs

1 code implementation22 Nov 2023 Viraj Shah, Nataniel Ruiz, Forrester Cole, Erika Lu, Svetlana Lazebnik, Yuanzhen Li, Varun Jampani

Experiments on a wide range of subject and style combinations show that ZipLoRA can generate compelling results with meaningful improvements over baselines in subject and style fidelity while preserving the ability to recontextualize.

Background Prompting for Improved Object Depth

no code implementations8 Jun 2023 Manel Baradad, Yuanzhen Li, Forrester Cole, Michael Rubinstein, Antonio Torralba, William T. Freeman, Varun Jampani

To infer object depth on a real image, we place the segmented object into the learned background prompt and run off-the-shelf depth networks.

Omnimatte3D: Associating Objects and Their Effects in Unconstrained Monocular Video

no code implementations CVPR 2023 Mohammed Suhail, Erika Lu, Zhengqi Li, Noah Snavely, Leonid Sigal, Forrester Cole

Instead, our method applies recent progress in monocular camera pose and depth estimation to create a full, RGBD video layer for the background, along with a video layer for each foreground object.

SCOOP: Self-Supervised Correspondence and Optimization-Based Scene Flow

1 code implementation CVPR 2023 Itai Lang, Dror Aiger, Forrester Cole, Shai Avidan, Michael Rubinstein

Scene flow estimation is a long-standing problem in computer vision, where the goal is to find the 3D motion of a scene from its consecutive observations.

DynIBaR: Neural Dynamic Image-Based Rendering

1 code implementation CVPR 2023 Zhengqi Li, Qianqian Wang, Forrester Cole, Richard Tucker, Noah Snavely

Our system retains the advantages of prior methods in its ability to model complex scenes and view-dependent effects, but also enables synthesizing photo-realistic novel views from long videos featuring complex scene dynamics with unconstrained camera trajectories.

D$^2$NeRF: Self-Supervised Decoupling of Dynamic and Static Objects from a Monocular Video

no code implementations31 May 2022 Tianhao Wu, Fangcheng Zhong, Andrea Tagliasacchi, Forrester Cole, Cengiz Oztireli

We introduce Decoupled Dynamic Neural Radiance Field (D$^2$NeRF), a self-supervised approach that takes a monocular video and learns a 3D scene representation which decouples moving objects, including their shadows, from the static background.

ViSER: Video-Specific Surface Embeddings for Articulated 3D Shape Reconstruction

1 code implementation NeurIPS 2021 Gengshan Yang, Deqing Sun, Varun Jampani, Daniel Vlasic, Forrester Cole, Ce Liu, Deva Ramanan

The surface embeddings are implemented as coordinate-based MLPs that are fit to each video via consistency and contrastive reconstruction losses. Experimental results show that ViSER compares favorably against prior work on challenging videos of humans with loose clothing and unusual poses as well as animals videos from DAVIS and YTVOS.

Differentiable Surface Rendering via Non-Differentiable Sampling

no code implementations ICCV 2021 Forrester Cole, Kyle Genova, Avneesh Sud, Daniel Vlasic, Zhoutong Zhang

We present a method for differentiable rendering of 3D surfaces that supports both explicit and implicit representations, provides derivatives at occlusion boundaries, and is fast and simple to implement.

Consistent Depth of Moving Objects in Video

no code implementations2 Aug 2021 Zhoutong Zhang, Forrester Cole, Richard Tucker, William T. Freeman, Tali Dekel

We present a method to estimate depth of a dynamic scene, containing arbitrary moving objects, from an ordinary video captured with a moving camera.

Omnimatte: Associating Objects and Their Effects in Video

no code implementations CVPR 2021 Erika Lu, Forrester Cole, Tali Dekel, Andrew Zisserman, William T. Freeman, Michael Rubinstein

We show results on real-world videos containing interactions between different types of subjects (cars, animals, people) and complex effects, ranging from semi-transparent elements such as smoke and reflections, to fully opaque effects such as objects attached to the subject.

Layered Neural Rendering for Retiming People in Video

1 code implementation16 Sep 2020 Erika Lu, Forrester Cole, Tali Dekel, Weidi Xie, Andrew Zisserman, David Salesin, William T. Freeman, Michael Rubinstein

We present a method for retiming people in an ordinary, natural video -- manipulating and editing the time in which different motions of individuals in the video occur.

Local Deep Implicit Functions for 3D Shape

1 code implementation CVPR 2020 Kyle Genova, Forrester Cole, Avneesh Sud, Aaron Sarna, Thomas Funkhouser

The goal of this project is to learn a 3D shape representation that enables accurate surface reconstruction, compact storage, efficient computation, consistency for similar shapes, generalization across diverse shape categories, and inference from depth camera observations.

Learning Shape Templates with Structured Implicit Functions

1 code implementation ICCV 2019 Kyle Genova, Forrester Cole, Daniel Vlasic, Aaron Sarna, William T. Freeman, Thomas Funkhouser

To allow for widely varying geometry and topology, we choose an implicit surface representation based on composition of local shape elements.

Unsupervised Training for 3D Morphable Model Regression

2 code implementations CVPR 2018 Kyle Genova, Forrester Cole, Aaron Maschinot, Aaron Sarna, Daniel Vlasic, William T. Freeman

We train a regression network using these objectives, a set of unlabeled photographs, and the morphable model itself, and demonstrate state-of-the-art results.
