COMEDIAN: Self-Supervised Learning and Knowledge Distillation for Action Spotting using Transformers

1 code implementation • 3 Sep 2023 • Julien Denize, Mykola Liashuha, Jaonary Rabarisoa, Astrid Orcesi, Romain Hérault

We present COMEDIAN, a novel pipeline to initialize spatiotemporal transformers for action spotting, which involves self-supervised learning and knowledge distillation.

Similarity Contrastive Estimation for Image and Video Soft Contrastive Self-Supervised Learning

2 code implementations • 21 Dec 2022 • Julien Denize, Jaonary Rabarisoa, Astrid Orcesi, Romain Hérault

A good data representation should contain relations between the instances, or semantic similarity and dissimilarity, that contrastive learning harms by considering all negatives as noise.

KaliCalib: A Framework for Basketball Court Registration

no code implementations • 16 Sep 2022 • Adrien Maglo, Astrid Orcesi, Quoc Cuong Pham

Tracking the players and the ball in team sports is key to analyse the performance or to enhance the game watching experience with augmented reality.

Camera Calibration Data Augmentation

Efficient tracking of team sport players with few game-specific annotations

no code implementations • 8 Apr 2022 • Adrien Maglo, Astrid Orcesi, Quoc-Cuong Pham

Many tracking and reidentification methods have been proposed in the context of video surveillance.

Incremental Learning

Detecting Human-to-Human-or-Object (H2O) Interactions with DIABOLO

no code implementations • 7 Jan 2022 • Astrid Orcesi, Romaric Audigier, Fritz Poka Toukam, Bertrand Luvison

This can be an issue for HOI detection methods whose complexity depends on the number of people, targets or interactions.

Similarity Contrastive Estimation for Self-Supervised Soft Contrastive Learning

2 code implementations • 29 Nov 2021 • Julien Denize, Jaonary Rabarisoa, Astrid Orcesi, Romain Hérault, Stéphane Canu

To circumvent this issue, we propose a novel formulation of contrastive learning using semantic similarity between instances called Similarity Contrastive Estimation (SCE).

Contrastive Learning Representation Learning +4

Classifying All Interacting Pairs in a Single Shot

no code implementations • 13 Jan 2020 • Sanaa Chafik, Astrid Orcesi, Romaric Audigier, Bertrand Luvison

In this paper, we introduce a novel human interaction detection approach, based on CALIPSO (Classifying ALl Interacting Pairs in a Single shOt), a classifier of human-object interactions.
