3DiFACE: Diffusion-based Speech-driven 3D Facial Animation and Editing

no code implementations1 Dec 2023 Balamurugan Thambiraja, Sadegh Aliakbarian, Darren Cosker, Justus Thies

To enable stochasticity as well as motion editing, we propose a lightweight audio-conditioned diffusion model for 3D facial motion.

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

no code implementations ICCV 2023 Sadegh Aliakbarian, Fatemeh Saleh, David Collier, Pashmina Cameron, Darren Cosker

Generating both plausible and accurate full body avatar motion is the key to the quality of immersive experiences in mixed reality scenarios.

Probabilistic Human Mesh Recovery in 3D Scenes from Egocentric Views

1 code implementation ICCV 2023 Siwei Zhang, Qianli Ma, Yan Zhang, Sadegh Aliakbarian, Darren Cosker, Siyu Tang

One of the biggest challenges of this task is severe body truncation due to close social distances in egocentric scenarios, which brings large pose ambiguities for unseen body parts.

Imitator: Personalized Speech-driven 3D Facial Animation

no code implementations ICCV 2023 Balamurugan Thambiraja, Ikhsanul Habibie, Sadegh Aliakbarian, Darren Cosker, Christian Theobalt, Justus Thies

To address this, we present Imitator, a speech-driven facial expression synthesis method, which learns identity-specific details from a short input video and produces novel facial expressions matching the identity-specific speaking style and facial idiosyncrasies of the target actor.

FLAG: Flow-based 3D Avatar Generation from Sparse Observations

no code implementations CVPR 2022 Sadegh Aliakbarian, Pashmina Cameron, Federica Bogo, Andrew Fitzgibbon, Thomas J. Cashman

To represent people in mixed reality applications for collaboration and communication, we need to generate realistic and faithful avatar poses.

Probabilistic Tracklet Scoring and Inpainting for Multiple Object Tracking

no code implementations CVPR 2021 Fatemeh Saleh, Sadegh Aliakbarian, Hamid Rezatofighi, Mathieu Salzmann, Stephen Gould

Despite the recent advances in multiple object tracking (MOT), achieved by joint detection and tracking, dealing with long occlusions remains a challenge.

Deep Sequence Learning for Video Anticipation: From Discrete and Deterministic to Continuous and Stochastic

no code implementations9 Oct 2020 Sadegh Aliakbarian

Video anticipation is the task of predicting one/multiple future representation(s) given limited, partial observation.

Uncertainty Inspired RGB-D Saliency Detection

4 code implementations7 Sep 2020 Jing Zhang, Deng-Ping Fan, Yuchao Dai, Saeed Anwar, Fatemeh Saleh, Sadegh Aliakbarian, Nick Barnes

Our framework includes two main models: 1) a generator model, which maps the input image and latent variable to stochastic saliency prediction, and 2) an inference model, which gradually updates the latent variable by sampling it from the true or approximate posterior distribution.

A Stochastic Conditioning Scheme for Diverse Human Motion Prediction

no code implementations CVPR 2020 Sadegh Aliakbarian, Fatemeh Sadat Saleh, Mathieu Salzmann, Lars Petersson, Stephen Gould

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.

ArTIST: Autoregressive Trajectory Inpainting and Scoring for Tracking

no code implementations16 Apr 2020 Fatemeh Saleh, Sadegh Aliakbarian, Mathieu Salzmann, Stephen Gould

One of the core components in online multiple object tracking (MOT) frameworks is associating new detections with existing tracklets, typically done via a scoring function.

Mosaic Super-resolution via Sequential Feature Pyramid Networks

no code implementations15 Apr 2020 Mehrdad Shoeiby, Mohammad Ali Armin, Sadegh Aliakbarian, Saeed Anwar, Lars Petersson

Additionally, to the best of our knowledge, our method is the first specialized method to super-resolve mosaic images, whether it be multi-spectral or Bayer.

Contextually Plausible and Diverse 3D Human Motion Prediction

no code implementations ICCV 2021 Sadegh Aliakbarian, Fatemeh Sadat Saleh, Lars Petersson, Stephen Gould, Mathieu Salzmann

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.

Multi-FAN: Multi-Spectral Mosaic Super-Resolution Via Multi-Scale Feature Aggregation Network

no code implementations17 Sep 2019 Mehrdad Shoeiby, Sadegh Aliakbarian, Saeed Anwar, Lars Petersson

This mosaic image is then merged with the mosaic image generated by the SR network to produce a quantitatively superior image.
