Jul 2023 — Oct 2023
Visiting Student, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
I worked on enhancing the performance of NeRF across scenes of varying lengths, guided by Peter Wonka. My approach was inspired by LocalRF, so I divided the scene into several parts and trained a NeRF model on each segment independently. I development of a model that surpassed LocalRF in performance on long scenes from the F2-NeRF dataset, achieving an average improvement of 1 PSNR. Additionally, it matched LocalRF’s quality on their ‘Static Hikes’ dataset. Notably, the training time for my model was 4 times less than that of LocalRF.

Research Intern, Center for Cognitive Modeling MIPT, Moscow, Russia
I enhanced Semantic NeRF under the supervision of Prof. Dmitry Yudin. I combined ideas from Instant-NGP into Semantic NeRF’s architecture. I also added uncertainty estimation for 3D reconstruction and semantic maps prediction. I have a pre-print as a result of my internship

uSF: Learning Neural Semantic Field with Uncertainty
Vsevolod Skorokhodov, Darya Drozdova, Dmitry Yudin
Abstract: Recently, there has been an increased interest in NeRF meth- ods which reconstruct differentiable representation of three-dimensional scenes. One of the main limitations of such methods is their inability to assess the confidence of the model in its predictions. In this paper, we propose a new neural network model for the formation of extended vector representations, called uSF, which allows the model to predict not only color and semantic label of each point, but also estimate the correspond- ing values of uncertainty. We show that with a small number of images available for training, a model quantifying uncertainty performs better than a model without such functionality
