FlowMap: High-Quality Camera Poses, Intrinsics, and Depth via Gradient Descent

1 code implementation23 Apr 2024 Cameron Smith, David Charatan, Ayush Tewari, Vincent Sitzmann

This paper introduces FlowMap, an end-to-end differentiable method that solves for precise camera poses, camera intrinsics, and per-frame dense depth of a video sequence.

SmartMask: Context Aware High-Fidelity Mask Generation for Fine-grained Object Insertion and Layout Control

no code implementations8 Dec 2023 Jaskirat Singh, Jianming Zhang, Qing Liu, Cameron Smith, Zhe Lin, Liang Zheng

To overcome these limitations, we introduce SmartMask, which allows any novice user to create detailed masks for precise object insertion.

Learning to Render Novel Views from Wide-Baseline Stereo Pairs

1 code implementation CVPR 2023 Yilun Du, Cameron Smith, Ayush Tewari, Vincent Sitzmann

We conduct extensive comparisons on held-out test scenes across two real-world datasets, significantly outperforming prior work on novel view synthesis from sparse image observations and achieving multi-view-consistent novel view synthesis.

In-N-Out: Faithful 3D GAN Inversion with Volumetric Decomposition for Face Editing

no code implementations9 Feb 2023 Yiran Xu, Zhixin Shu, Cameron Smith, Seoung Wug Oh, Jia-Bin Huang

3D-aware GANs offer new capabilities for view synthesis while preserving the editing functionalities of their 2D counterparts.

Algebraic structure of hierarchic first-order reaction networks applicable to models of clone size distribution and stochastic gene expression

no code implementations2 Feb 2023 Ximo Pechuan-Jorge, Raymond S. Puzio, Cameron Smith

Crucially, we identify the fact that the Lie group associated to hierarchic reaction networks decomposes as a wreath product of the groups associated to the subnetworks of the independent and dependent types.

Paint2Pix: Interactive Painting based Progressive Image Synthesis and Editing

1 code implementation17 Aug 2022 Jaskirat Singh, Liang Zheng, Cameron Smith, Jose Echevarria

In particular, we propose a novel approach paint2pix, which learns to predict (and adapt) "what a user wants to draw" from rudimentary brushstroke inputs, by learning a mapping from the manifold of incomplete human paintings to their realistic renderings.

Unsupervised Discovery and Composition of Object Light Fields

no code implementations8 May 2022 Cameron Smith, Hong-Xing Yu, Sergey Zakharov, Fredo Durand, Joshua B. Tenenbaum, Jiajun Wu, Vincent Sitzmann

Neural scene representations, both continuous and discrete, have recently emerged as a powerful new paradigm for 3D scene understanding.

Intelli-Paint: Towards Developing Human-like Painting Agents

no code implementations16 Dec 2021 Jaskirat Singh, Cameron Smith, Jose Echevarria, Liang Zheng

However, current research in this direction is often reliant on a progressive grid-based division strategy wherein the agent divides the overall image into successively finer grids, and then proceeds to paint each of them in parallel.

Experimentally testable whole brain manifolds that recapitulate behavior

no code implementations20 Jun 2021 Gerald M Pao, Cameron Smith, Joseph Park, Keichi Takahashi, Wassapon Watanakeesuntorn, Hiroaki Natsukawa, Sreekanth H Chalasani, Tom Lorimer, Ryousei Takano, Nuttida Rungratsameetaweemana, George Sugihara

Thus, as a final validation of how well GMN captures essential dynamic information, we show that the artificially generated time series can be used as a training set to predict out-of-sample observed fly locomotion, as well as brain activity in out of sample withheld data not used in model building.

MaterialGAN: Reflectance Capture using a Generative SVBRDF Model

no code implementations30 Sep 2020 Yu Guo, Cameron Smith, Miloš Hašan, Kalyan Sunkavalli, Shuang Zhao

We address the problem of reconstructing spatially-varying BRDFs from a small set of image measurements.
