StableDreamer: Taming Noisy Score Distillation Sampling for Text-to-3D

no code implementations2 Dec 2023 Pengsheng Guo, Hans Hao, Adam Caccavale, Zhongzheng Ren, Edward Zhang, Qi Shan, Aditya Sankar, Alexander G. Schwing, Alex Colburn, Fangchang Ma

Our analysis identifies the core of these challenges as the interaction among noise levels in the 2D diffusion process, the architecture of the diffusion network, and the 3D model representation.

Pseudo-Generalized Dynamic View Synthesis from a Video

no code implementations12 Oct 2023 Xiaoming Zhao, Alex Colburn, Fangchang Ma, Miguel Angel Bautista, Joshua M. Susskind, Alexander G. Schwing

In contrast, for dynamic scenes, scene-specific optimization techniques exist, but, to our best knowledge, there is currently no generalized method for dynamic novel view synthesis from a given monocular video.

AutoFocusFormer: Image Segmentation off the Grid

1 code implementation CVPR 2023 Chen Ziwen, Kaushik Patnaik, Shuangfei Zhai, Alvin Wan, Zhile Ren, Alex Schwing, Alex Colburn, Li Fuxin

To achieve this, we propose AutoFocusFormer (AFF), a local-attention transformer image recognition backbone, which performs adaptive downsampling by learning to retain the most important pixels for the task.

FineRecon: Depth-aware Feed-forward Network for Detailed 3D Reconstruction

1 code implementation ICCV 2023 Noah Stier, Anurag Ranjan, Alex Colburn, Yajie Yan, Liang Yang, Fangchang Ma, Baptiste Angles

Recent works on 3D reconstruction from posed images have demonstrated that direct inference of scene-level 3D geometry without test-time optimization is feasible using deep neural networks, showing remarkable promise and high efficiency.

Fast and Explicit Neural View Synthesis

no code implementations12 Jul 2021 Pengsheng Guo, Miguel Angel Bautista, Alex Colburn, Liang Yang, Daniel Ulbricht, Joshua M. Susskind, Qi Shan

We study the problem of novel view synthesis from sparse source observations of a scene comprised of 3D objects.

Deep Neural Network Approach for Annual Luminance Simulations

no code implementations14 Sep 2020 Yue Liu, Alex Colburn, Mehlika Inanici

The proposed DNN model can faithfully predict high-quality annual panoramic luminance maps from one of the three options within 30 minutes training time: a) point-in-time luminance imagery spanning 5% of the year, when evenly distributed during daylight hours, b) one-month hourly imagery generated or collected continuously during daylight hours around the equinoxes (8% of the year); or c) 9 days of hourly data collected around the spring equinox, summer and winter solstices (2. 5% of the year) all suffice to predict the luminance maps for the rest of the year.

Equivariant Neural Rendering

1 code implementation ICML 2020 Emilien Dupont, Miguel Angel Bautista, Alex Colburn, Aditya Sankar, Carlos Guestrin, Josh Susskind, Qi Shan

We propose a framework for learning neural scene representations directly from images, without 3D supervision.

Learning Stylized Character Expressions from Humans

no code implementations19 Nov 2019 Deepali Aneja, Alex Colburn, Gary Faigin, Linda Shapiro, Barbara Mones

We present DeepExpr, a novel expression transfer system from humans to multiple stylized characters via deep learning.

LayoutNet: Reconstructing the 3D Room Layout from a Single RGB Image

2 code implementations CVPR 2018 Chuhang Zou, Alex Colburn, Qi Shan, Derek Hoiem

We propose an algorithm to predict room layout from a single image that generalizes across panoramas and perspective images, cuboid layouts and more general layouts (e. g. L-shape room).
