TIM: A Time Interval Machine for Audio-Visual Action Recognition

2 code implementations8 Apr 2024 Jacob Chalk, Jaesung Huh, Evangelos Kazakos, Andrew Zisserman, Dima Damen

We address the interplay between the two modalities in long videos by explicitly modelling the temporal extents of audio and visual events.

Graph Guided Question Answer Generation for Procedural Question-Answering

no code implementations24 Jan 2024 Hai X. Pham, Isma Hadji, Xinnuo Xu, Ziedune Degutyte, Jay Rainey, Evangelos Kazakos, Afsaneh Fazly, Georgios Tzimiropoulos, Brais Martinez

The key technological enabler is a novel mechanism for automatic question-answer generation from procedural text which can ingest large amounts of textual instructions and produce exhaustive in-domain QA training data.

Epic-Sounds: A Large-scale Dataset of Actions That Sound

1 code implementation1 Feb 2023 Jaesung Huh, Jacob Chalk, Evangelos Kazakos, Dima Damen, Andrew Zisserman

We introduce EPIC-SOUNDS, a large-scale dataset of audio annotations capturing temporal extents and class labels within the audio stream of the egocentric videos.

With a Little Help from my Temporal Context: Multimodal Egocentric Action Recognition

1 code implementation1 Nov 2021 Evangelos Kazakos, Jaesung Huh, Arsha Nagrani, Andrew Zisserman, Dima Damen

We capitalise on the action's temporal context and propose a method that learns to attend to surrounding actions in order to improve recognition performance.

Slow-Fast Auditory Streams For Audio Recognition

2 code implementations5 Mar 2021 Evangelos Kazakos, Arsha Nagrani, Andrew Zisserman, Dima Damen

We propose a two-stream convolutional network for audio recognition, that operates on time-frequency spectrogram inputs.

The EPIC-KITCHENS Dataset: Collection, Challenges and Baselines

2 code implementations29 Apr 2020 Dima Damen, Hazel Doughty, Giovanni Maria Farinella, Sanja Fidler, Antonino Furnari, Evangelos Kazakos, Davide Moltisanti, Jonathan Munro, Toby Perrett, Will Price, Michael Wray

Our dataset features 55 hours of video consisting of 11. 5M frames, which we densely labelled for a total of 39. 6K action segments and 454. 2K object bounding boxes.


EPIC-Fusion: Audio-Visual Temporal Binding for Egocentric Action Recognition

1 code implementation ICCV 2019 Evangelos Kazakos, Arsha Nagrani, Andrew Zisserman, Dima Damen

We focus on multi-modal fusion for egocentric action recognition, and propose a novel architecture for multi-modal temporal-binding, i. e. the combination of modalities within a range of temporal offsets.

Human Activity Recognition Using Robust Adaptive Privileged Probabilistic Learning

no code implementations19 Sep 2017 Michalis Vrigkas, Evangelos Kazakos, Christophoros Nikou, Ioannis A. Kakadiaris

In this work, a novel method based on the learning using privileged information (LUPI) paradigm for recognizing complex human activities is proposed that handles missing information during testing.

Inferring Human Activities Using Robust Privileged Probabilistic Learning

no code implementations31 Aug 2017 Michalis Vrigkas, Evangelos Kazakos, Christophoros Nikou, Ioannis A. Kakadiaris

Classification models may often suffer from "structure imbalance" between training and testing data that may occur due to the deficient data collection process.
