Rembert Daems

Computer vision and machine learning researcher


I'm currently at an early-stage medtech startup; before that I was a postdoc in the group of Thomas Demeester. My PhD was on the intersection of visual perception, (stochastic) dynamical systems and physics priors. I started ongoing collaborations with Tolga Birdal and Manfred Opper on SDEs driven by fractional Brownian motion, leading to an ICLR spotlight, and subsequent work led by Gabriel Nobis on generative fractional diffusion models and fractional Schrödinger bridges.

During my PhD I co-founded Hippo Dx, a medical-device start-up behind the automated skin prick test (SPAT), where I worked on the camera and lighting system, image processing and AI-assisted diagnostics. Before my PhD I worked as innovation engineer at CNH Industrial on combine-harvester automation, and as AI lead at Octinion on agricultural computer vision projects.

I live in Brugge with my wife and three kids.

FDBM unpaired image translation: wild → domestic cat
Fractional Diffusion Bridge Models
Gabriel Nobis, Maximilian Springenberg, Arina Belova, Rembert Daems, Christoph Knochenhauer, Manfred Opper, Tolga Birdal, Wojciech Samek

Advances in Neural Information Processing Systems (NeurIPS), 2025

A generative diffusion-bridge framework driven by an approximation of non-Markovian fractional Brownian motion, capturing the memory and long-range dependence that standard Brownian-motion bridges miss.

CCPose: from a multi-view image of texture-less industrial objects to predicted center and curvature heatmaps and estimated 6D poses
CCPose: High-Precision Six-Dimensional Pose Estimation for Industrial Objects
Peter De Roovere, Rembert Daems, Jonathan Croenen, Francis wyffels

Machine Vision and Applications, 2025

A three-stage method for 6D pose estimation of texture-less industrial objects: predicting center and curvature heatmaps with a fully convolutional network, triangulating 3D object centers across views, then refining poses by render-and-compare; it reaches millimeter-level, state-of-the-art accuracy on T-LESS and is deployed in a real robotic pick-and-place system.

Nature Communications, 2025

An AI-assisted readout method that measures wheal diameters from Skin Prick Automated Test (SPAT) images, validated against physician measurements, to support consistent allergy diagnosis.

Generative Fractional Diffusion Models teaser: OU density with score-based reverse SDE
Generative Fractional Diffusion Models
Gabriel Nobis, Maximilian Springenberg, Marco Aversa, Michael Detzel, Rembert Daems, Roderick Murray-Smith, Shinichi Nakajima, Sebastian Lapuschkin, Stefano Ermon, Tolga Birdal, Manfred Opper, Christoph Knochenhauer, Luis Oala, Wojciech Samek

Advances in Neural Information Processing Systems (NeurIPS), 2024

The first continuous-time score-based generative model driven by fractional diffusion: replacing Brownian motion with fractional Brownian motion (Hurst index H) for better diversity and convergence.
paper
Variational SDE teaser
Variational Inference for SDEs Driven by Fractional Noise
Rembert Daems, Manfred Opper, Guillaume Crevecoeur, Tolga Birdal

The Twelfth International Conference on Learning Representations (ICLR), 2024

The first variational inference framework for non-Markovian neural SDEs driven by fractional Brownian motion, approximating the fBM by a linear combination of Markov processes; derives the variational posterior and ELBO.

KeyCLD predictions
KeyCLD: Learning constrained Lagrangian dynamics in keypoint coordinates from images
Rembert Daems, Jeroen Taets, Guillaume Crevecoeur, Francis wyffels

Neurocomputing, 2024

Learns Lagrangian dynamics from images: keypoints give Cartesian coordinates with explicit holonomic constraints, trained unsupervised end-to-end, enabling long-term video prediction and energy-based control.

Unsupervised orientation of planes
Unsupervised Orientation Learning Using Autoencoders
Rembert Daems, Francis wyffels

Differential Geometry meets Deep Learning (DiffGeo4DL NeurIPS Workshop), 2020

An unsupervised method to learn the orientation of symmetric objects in images, mapping in-plane rotations into an autoencoder's latent space via a crossing loss, disentangling orientation from other factors.
