MoCap-guided Data Augmentation for 3D Pose Estimation in the Wild

no code implementations NeurIPS 2016 Grégory Rogez, Cordelia Schmid

Here, we propose a solution to generate a large set of photorealistic synthetic images of humans with 3D pose annotations.

Detecting Parts for Action Localization

no code implementations19 Jul 2017 Nicolas Chesneau, Grégory Rogez, Karteek Alahari, Cordelia Schmid

In this paper, we propose a new framework for action localization that tracks people in videos and extracts full-body human tubes, i. e., spatio-temporal regions localizing actions, even in the case of occlusions or truncations.

Mimetics: Towards Understanding Human Actions Out of Context

no code implementations16 Dec 2019 Philippe Weinzaepfel, Grégory Rogez

Our experiments show that (a) state-of-the-art 3D convolutional neural networks obtain disappointing results on such videos, highlighting the lack of true understanding of the human actions and (b) models leveraging body language via human pose are less prone to context biases.

DOPE: Distillation Of Part Experts for whole-body 3D pose estimation in the wild

1 code implementation ECCV 2020 Philippe Weinzaepfel, Romain Brégier, Hadrien Combaluzier, Vincent Leroy, Grégory Rogez

We introduce DOPE, the first method to detect and estimate whole-body 3D human poses, including bodies, hands and faces, in the wild.

Continual Adaptation of Visual Representations via Domain Randomization and Meta-learning

no code implementations CVPR 2021 Riccardo Volpi, Diane Larlus, Grégory Rogez

In this context, we show that one way to learn models that are inherently more robust against forgetting is domain randomization - for vision tasks, randomizing the current domain's distribution with heavy image manipulations.

Towards fast and effective single-step adversarial training

no code implementations29 Sep 2021 Pau de Jorge, Adel Bibi, Riccardo Volpi, Amartya Sanyal, Philip Torr, Grégory Rogez, Puneet K. Dokania

In this work, we methodically revisit the role of noise and clipping in single-step adversarial training.

Make Some Noise: Reliable and Efficient Single-Step Adversarial Training

1 code implementation2 Feb 2022 Pau de Jorge, Adel Bibi, Riccardo Volpi, Amartya Sanyal, Philip H. S. Torr, Grégory Rogez, Puneet K. Dokania

Recently, Wong et al. showed that adversarial training with single-step FGSM leads to a characteristic failure mode named Catastrophic Overfitting (CO), in which a model becomes suddenly vulnerable to multi-step attacks.

PoseBERT: A Generic Transformer Module for Temporal 3D Human Modeling

1 code implementation22 Aug 2022 Fabien Baradel, Romain Brégier, Thibault Groueix, Philippe Weinzaepfel, Yannis Kalantidis, Grégory Rogez

It is simple, generic and versatile, as it can be plugged on top of any image-based model to transform it in a video-based model leveraging temporal information.

PoseGPT: Quantization-based 3D Human Motion Generation and Forecasting

1 code implementation19 Oct 2022 Thomas Lucas, Fabien Baradel, Philippe Weinzaepfel, Grégory Rogez

The discrete and compressed nature of the latent space allows the GPT-like model to focus on long-range signal, as it removes low-level redundancy in the input signal.

PoseFix: Correcting 3D Human Poses with Natural Language

no code implementations ICCV 2023 Ginger Delmas, Philippe Weinzaepfel, Francesc Moreno-Noguer, Grégory Rogez

Automatically producing instructions to modify one's posture could open the door to endless applications, such as personalized coaching and in-home physical therapy.

Cross-view and Cross-pose Completion for 3D Human Understanding

no code implementations15 Nov 2023 Matthieu Armando, Salma Galaaoui, Fabien Baradel, Thomas Lucas, Vincent Leroy, Romain Brégier, Philippe Weinzaepfel, Grégory Rogez

Human perception and understanding is a major domain of computer vision which, like many other vision subdomains recently, stands to gain from the use of large models pre-trained on large datasets.
