Efficient End-to-End Video Question Answering with Pyramidal Multimodal Transformer

1 code implementation4 Feb 2023 Min Peng, Chongyang Wang, Yu Shi, Xiang-Dong Zhou

This paper presents a new method for end-to-end Video Question Answering (VideoQA), aside from the current popularity of using large-scale pre-training with huge feature extractors.

Multilevel Hierarchical Network with Multiscale Sampling for Video Question Answering

1 code implementation9 May 2022 Min Peng, Chongyang Wang, Yuan Gao, Yu Shi, Xiang-Dong Zhou

With a multiscale sampling, RMI iterates the interaction of appearance-motion information at each scale and the question embeddings to build the multilevel question-guided visual representations.

Learn2Agree: Fitting with Multiple Annotators without Objective Ground Truth

no code implementations8 Sep 2021 Chongyang Wang, Yuan Gao, Chenyou Fan, Junjie Hu, Tin Lun Lam, Nicholas D. Lane, Nadia Bianchi-Berthouze

For such issues, we propose a novel Learning to Agreement (Learn2Agree) framework to tackle the challenge of learning from multiple annotators without objective ground truth.

Leveraging Activity Recognition to Enable Protective Behavior Detection in Continuous Data

1 code implementation3 Nov 2020 Chongyang Wang, Yuan Gao, Akhil Mathur, Amanda C. De C. Williams, Nicholas D. Lane, Nadia Bianchi-Berthouze

Protective behavior exhibited by people with chronic pain (CP) during physical activities is the key to understanding their physical and emotional states.

Recognizing Micro-Expression in Video Clip with Adaptive Key-Frame Mining

1 code implementation19 Sep 2020 Min Peng, Chongyang Wang, Yuan Gao, Tao Bi, Tong Chen, Yu Shi, Xiang-Dong Zhou

As a spontaneous expression of emotion on face, micro-expression reveals the underlying emotion that cannot be controlled by human.

EMOPAIN Challenge 2020: Multimodal Pain Evaluation from Facial and Bodily Expressions

no code implementations21 Jan 2020 Joy O. Egede, Siyang Song, Temitayo A. Olugbade, Chongyang Wang, Amanda Williams, Hongy-ing Meng, Min Aung, Nicholas D. Lane, Michel Valstar, Nadia Bianchi-Berthouze

The EmoPain 2020 Challenge is the first international competition aimed at creating a uniform platform for the comparison of machine learning and multimedia processing methods of automatic chronic pain assessment from human expressive behaviour, and also the identification of pain-related behaviours.

Learning Bodily and Temporal Attention in Protective Movement Behavior Detection

1 code implementation24 Apr 2019 Chongyang Wang, Min Peng, Temitayo A. Olugbade, Nicholas D. Lane, Amanda C. De C. Williams, Nadia Bianchi-Berthouze

For people with chronic pain, the assessment of protective behavior during physical functioning is essential to understand their subjective pain-related experiences (e. g., fear and anxiety toward pain and injury) and how they deal with such experiences (avoidance or reliance on specific body joints), with the ultimate goal of guiding intervention.

A Novel Apex-Time Network for Cross-Dataset Micro-Expression Recognition

1 code implementation7 Apr 2019 Min Peng, Chongyang Wang, Tao Bi, Tong Chen, Xiangdong Zhou, Yu Shi

As researchers working on such topics are moving to learn from the nature of micro-expression, the practice of using deep learning techniques has evolved from processing the entire video clip of micro-expression to the recognition on apex frame.

Chronic-Pain Protective Behavior Detection with Deep Learning

1 code implementation24 Feb 2019 Chongyang Wang, Temitayo A. Olugbade, Akhil Mathur, Amanda C. De C. Williams, Nicholas D. Lane, Nadia Bianchi-Berthouze

In chronic pain rehabilitation, physiotherapists adapt physical activity to patients' performance based on their expression of protective behavior, gradually exposing them to feared but harmless and essential everyday activities.

Micro-Attention for Micro-Expression recognition

1 code implementation6 Nov 2018 Chongyang Wang, Min Peng, Tao Bi, Tong Chen

The existence of micro expression in small-local areas on face and limited size of available databases still constrain the recognition accuracy on such emotional facial behavior.
