Ice-Tide: Implicit Cryo-ET Imaging and Deformation Estimation

1 code implementation4 Mar 2024 Valentin Debarnot, Vinith Kishore, Ricardo D. Righetto, Ivan Dokmanić

We introduce ICE-TIDE, a method for cryogenic electron tomography (cryo-ET) that simultaneously aligns observations and reconstructs a high-resolution volume.

GLIMPSE: Generalized Local Imaging with MLPs

1 code implementation1 Jan 2024 AmirEhsan Khorashadizadeh, Valentin Debarnot, Tianlin Liu, Ivan Dokmanić

Deep learning is the current de facto state of the art in tomographic imaging.

Implicit Reconstructions from Deformed Projections for CryoET

no code implementations25 Jul 2023 Vinith Kishore, Valentin Debarnot, Ivan Dokmanić

Cryo-electron tomography (cryoET) is a technique that captures images of biological samples at different tilts, preserving their native state as much as possible.

FunkNN: Neural Interpolation for Functional Generation

1 code implementation20 Dec 2022 AmirEhsan Khorashadizadeh, Anadi Chaman, Valentin Debarnot, Ivan Dokmanić

Our answer is FunkNN -- a new convolutional network which learns how to reconstruct continuous images at arbitrary coordinates and can be applied to any image dataset.

Joint Cryo-ET Alignment and Reconstruction with Neural Deformation Fields

no code implementations26 Nov 2022 Valentin Debarnot, Sidharth Gupta, Konik Kothari, Ivan Dokmanic

We show that our approach enables the recovery of high-frequency details that are destroyed without accounting for deformations.

Differentiable Uncalibrated Imaging

1 code implementation18 Nov 2022 Sidharth Gupta, Konik Kothari, Valentin Debarnot, Ivan Dokmanić

We propose a differentiable imaging framework to address uncertainty in measurement coordinates such as sensor locations and projection angles.

Image Reconstruction

Small Transformers Compute Universal Metric Embeddings

1 code implementation NeurIPS 2023 Anastasis Kratsios, Valentin Debarnot, Ivan Dokmanić

We derive embedding guarantees for feature maps implemented by small neural networks called \emph{probabilistic transformers}.

Memorization

Manifold Rewiring for Unlabeled Imaging

no code implementations12 Sep 2022 Valentin Debarnot, Vinith Kishore, Cheng Shi, Ivan Dokmanić

We illustrate our graph denoising framework on regular synthetic graphs and then apply it to single-particle cryo-EM where the measurements are corrupted by very high levels of noise.

Blind inverse problems with isolated spikes

no code implementations3 Nov 2021 Valentin Debarnot, Pierre Weiss

Assume that an unknown integral operator living in some known subspace is observed indirectly, by evaluating its action on a few Dirac masses at unknown locations.
