Template-free Articulated Neural Point Clouds for Reposable View Synthesis

NeurIPS 2023poster

Dynamic Neural Radiance Fields (NeRFs) achieve remarkable visual quality when synthesizing novel views of time-evolving 3D scenes. However, the common reliance on backward deformation fields makes reanimation of the captured object poses challenging. Moreover, the state of the art dynamic models are…

Generative Neural Articulated Radiance Fields

NeurIPS 2022accept

Unsupervised learning of 3D-aware generative adversarial networks (GANs) using only collections of single-view 2D photographs has very recently made much progress. These 3D GANs, however, have not been demonstrated for human bodies and the generated radiance fields of existing frameworks are not dir…

Fast Training of Neural Lumigraph Representations using Meta Learning

NeurIPS 2021poster

Novel view synthesis is a long-standing problem in machine learning and computer vision. Significant progress has recently been made in developing neural scene representations and rendering techniques that synthesize photorealistic images from arbitrary views. These representations, however, are ext…

Pi-GAN: Periodic Implicit Generative Adversarial Networks for 3D-Aware Image Synthesis

CVPR 2021poster

We have witnessed rapid progress on 3D-aware image synthesis, leveraging recent advances in generative visual models and neural rendering. Existing approaches however fall short in two ways: first, they may lack an underlying 3D representation or rely on view-inconsistent rendering, hence synthesizi…

Gaze360: Physically Unconstrained Gaze Estimation in the Wild

ICCV 2019poster

Understanding where people are looking is an informative social cue. In this work, we present Gaze360, a large-scale remote gaze-tracking dataset and method for robust 3D gaze estimation in unconstrained images. Our dataset consists of 238 subjects in indoor and outdoor environments with labelled 3D…

Neural Inverse Knitting: From Images to Manufacturing Instructions

ICML 2019oral

Motivated by the recent potential of mass customization brought by whole-garment knitting machines, we introduce the new problem of automatic machine instruction generation using a single image of the desired physical product, which we apply to machine knitting. We propose to tackle this problem by…

A Dataset of Flash and Ambient Illumination Pairs from the Crowd

ECCV 2018poster

Illumination is a critical element of photography and is essential for many computer vision tasks. Flash light is unique in the sense that it is a widely available tool for easily manipulating the scene illumination. We present a dataset of thousands of ambient and flash illumination pairs to enable…

Learning to Zoom: a Saliency-Based Sampling Layer for Neural Networks

ECCV 2018poster

We introduce a saliency-based distortion layer for convolutional neural networks that helps to improve the spatial sampling of input data for a given task. Our differentiable layer can be added as a preprocessing block to existing task networks and trained altogether in an end-to-end fashion. The ef…

Eye Tracking for Everyone

CVPR 2016poster

From scientific research to commercial applications, eye tracking is an important tool across many domains. Despite its range of applications, eye tracking has yet to become a pervasive technology. We believe that we can put the power of eye tracking in everyone's palm by building eye tracking softw…
