DAViD: Data-efficient and Accurate Vision Models from Synthetic Data

ICCV 2025poster

The state of the art in human-centric computer vision achieves high accuracy and robustness across a diverse range of tasks. The most effective models in this domain have billions of parameters, thus requiring extremely large datasets, expensive training regimes, and compute-intensive inference. In…

HMD-NeMo: Online 3D Avatar Motion Generation From Sparse Observations

ICCV 2023poster

Generating both plausible and accurate full body avatar motion is the key to the quality of immersive experiences in mixed reality scenarios. Head-Mounted Devices (HMDs) typically only provide a few input signals, such as head and hands 6-DoF. Recently, different approaches achieved impressive perfo…

Imitator: Personalized Speech-driven 3D Facial Animation

ICCV 2023poster

Speech-driven 3D facial animation has been widely explored, with applications in gaming, character animation, virtual reality, and telepresence systems. State-of-the-art methods deform the face topology of the target actor to sync the input audio without considering the identity-specific speaking st…

Probabilistic Human Mesh Recovery in 3D Scenes from Egocentric Views

ICCV 2023oral

Automatic perception of human behaviors during social interactions is crucial for AR/VR applications, and an essential component is estimation of plausible 3D human pose and shape of our social partners from the egocentric view. One of the biggest challenges of this task is severe body truncation du…

FLAG: Flow-Based 3D Avatar Generation From Sparse Observations

CVPR 2022poster

To represent people in mixed reality applications for collaboration and communication, we need to generate realistic and faithful avatar poses. However, the signal streams that can be applied for this task from head-mounted devices (HMDs) are typically limited to head pose and hand pose estimates. W…

Contextually Plausible and Diverse 3D Human Motion Prediction

ICCV 2021poster

We tackle the task of diverse 3D human motion prediction, that is, forecasting multiple plausible future 3D poses given a sequence of observed 3D poses. In this context, a popular approach consists of using a Conditional Variational Autoencoder (CVAE). However, existing approaches that do so either…

Probabilistic Tracklet Scoring and Inpainting for Multiple Object Tracking

CVPR 2021poster

Despite the recent advances in multiple object tracking (MOT), achieved by joint detection and tracking, dealing with long occlusions remains a challenge. This is due to the fact that such techniques tend to ignore the long-term motion information. In this paper, we introduce a probabilistic autoreg…

A Stochastic Conditioning Scheme for Diverse Human Motion Prediction

CVPR 2020poster

Human motion prediction, the task of predicting future 3D human poses given a sequence of observed ones, has been mostly treated as a deterministic problem. However, human motion is a stochastic process: Given an observed sequence of poses, multiple future motions are plausible. Existing approaches…
