ActNetFormer: Transformer-ResNet Hybrid Method for Semi-Supervised Action Recognition in Videos

2 code implementations9 Apr 2024 Sharana Dharshikgan Suresh Dass, Hrishav Bakul Barua, Ganesh Krishnasamy, Raveendran Paramesran, Raphael C. -W. Phan

Our framework leverages both labeled and unlabelled data to robustly learn action representations in videos, combining pseudo-labeling with contrastive learning for effective learning from both types of samples.

Transferable Class-Modelling for Decentralized Source Attribution of GAN-Generated Images

1 code implementation18 Mar 2022 Brandon B. G. Khoo, Chern Hong Lim, Raphael C. -W. Phan

GAN-generated deepfakes as a genre of digital images are gaining ground as both catalysts of artistic expression and malicious forms of deception, therefore demanding systems to enforce and accredit their ethical use.

Less is More: Micro-expression Recognition from Video using Apex Frame

no code implementations6 Jun 2016 Sze-Teng Liong, John See, KokSheik Wong, Raphael C. -W. Phan

The apex frame of a video contains the highest intensity of expression changes among all frames, while the onset is the perfect choice of a reference frame with neutral expression.

Spontaneous expression classification in the encrypted domain

no code implementations14 Mar 2014 Segun Aina, Yogachandran Rahulamathavan, Raphael C. -W. Phan, Jonathon A. Chambers

To date, most facial expression analysis have been based on posed image databases and is carried out without being able to protect the identity of the subjects whose expressions are being recognised.
