NeRFuser: Large-Scale Scene Representation by NeRF Fusion

1 code implementation22 May 2023 Jiading Fang, Shengjie Lin, Igor Vasiljevic, Vitor Guizilini, Rares Ambrus, Adrien Gaidon, Gregory Shakhnarovich, Matthew R. Walter

A practical benefit of implicit visual representations like Neural Radiance Fields (NeRFs) is their memory efficiency: large scenes can be efficiently stored and shared as small neural nets instead of collections of images.

DeLiRa: Self-Supervised Depth, Light, and Radiance Fields

no code implementations ICCV 2023 Vitor Guizilini, Igor Vasiljevic, Jiading Fang, Rares Ambrus, Sergey Zakharov, Vincent Sitzmann, Adrien Gaidon

In this work, we propose to use the multi-view photometric objective from the self-supervised depth estimation literature as a geometric regularizer for volumetric rendering, significantly improving novel view synthesis without requiring additional information.

DIODE: A Dense Indoor and Outdoor DEpth Dataset

2 code implementations1 Aug 2019 Igor Vasiljevic, Nick Kolkin, Shanyi Zhang, Ruotian Luo, Haochen Wang, Falcon Z. Dai, Andrea F. Daniele, Mohammadreza Mostajabi, Steven Basart, Matthew R. Walter, Gregory Shakhnarovich

We introduce DIODE, a dataset that contains thousands of diverse high resolution color images with accurate, dense, long-range depth measurements.

Examining the Impact of Blur on Recognition by Convolutional Networks

no code implementations17 Nov 2016 Igor Vasiljevic, Ayan Chakrabarti, Gregory Shakhnarovich

We investigate the extent to which this degradation is due to the mismatch between training and input image statistics.
