Strength-Parity Ensembling with Parameter-Isolated Experts for Multi-Task Affect Recognition
Tung Hung Bui, Hong Hai Nguyen, Van Thong Huynh
Leading entries on the multi-task track of the 11th ABAW challenge rely on heavy ensembling, yet which member is worth adding to an already strong ensemble is rarely made explicit.…
CF-Net: Conflict Fusion with Speaker Normalisation and Certainty Weighting for Ambivalence/Hesitancy Recognition
Tung Hung Bui, Hong Hai Nguyen, Van Thong Huynh
Detecting ambivalence and hesitancy (AH) in unconstrained video is challenging because the target signal is inherently ambiguous and expressed through subtle cross-modal incongruen…
A Shared Latent for Partially-Labeled Multi-Task Facial Affect Recognition
Hong Hai Nguyen, Sy Phan Van, Soo-Hyung Kim +1
Facial affect in the wild is naturally multi-task: valence-arousal, discrete expressions, and facial action units describe the same face. Yet real corpora annotate these tasks only…
Faithful Action-unit Causal Reasoning for Counterfactually Faithful Emotion Explanations
Van Thong Huynh, Hong Hai Nguyen, Thuy Pham +2
Multimodal models can name the action units (AUs) behind a facial emotion, but their AU->emotion rationales are typically plausible rather than faithful: nothing forces the AUs a m…
The Circumplex Degeneracy Behind the Rare-Class Limit in Affect Recognition
Van Thong Huynh, Hong Hai Nguyen, Soo-Hyung Kim
In-the-wild expression recognition persistently fails on a few rare emotions, and the standard explanation is class imbalance. Through a controlled multi-task study on two benchmar…
Lightweight Models for Emotional Analysis in Video
Quoc-Tien Nguyen, Hong-Hai Nguyen, Van-Thong Huynh
In this study, we present an approach for efficient spatiotemporal feature extraction using MobileNetV4 and a multi-scale 3D MLP-Mixer-based temporal aggregation module. MobileNetV…
Adaptation of Distinct Semantics for Uncertain Areas in Polyp Segmentation
Quang Vinh Nguyen, Van Thong Huynh, Soo-Hyung Kim
Colonoscopy is a common and practical method for detecting and treating polyps. Segmenting polyps from colonoscopy image is useful for diagnosis and surgery progress. Nevertheless,…
Vision Transformer for Action Units Detection
Tu Vu, Van Thong Huynh, Soo Hyung Kim
Facial Action Units detection (FAUs) represents a fine-grained classification problem that involves identifying different units on the human face, as defined by the Facial Action C…
Generic Event Boundary Detection in Video with Pyramid Features
Van Thong Huynh, Hyung-Jeong Yang, Guee-Sang Lee +1
Generic event boundary detection (GEBD) aims to split video into chunks at a broad and diverse set of actions as humans naturally perceive event boundaries. In this study, we prese…
Facial Expression Classification using Fusion of Deep Neural Network in Video for the 3rd ABAW3 Competition
Kim Ngan Phan, Hong-Hai Nguyen, Van-Thong Huynh +1
For computers to recognize human emotions, expression classification is an equally important problem in the human-computer interaction area. In the 3rd Affective Behavior Analysis…
An Ensemble Approach for Facial Expression Analysis in Video
Hong-Hai Nguyen, Van-Thong Huynh, Soo-Hyung Kim
Human emotions recognization contributes to the development of human-computer interaction. The machines understanding human emotions in the real world will significantly contribute…
Temporal Convolution Networks with Positional Encoding for Evoked Expression Estimation
VanThong Huynh, Guee-Sang Lee, Hyung-Jeong Yang +1
This paper presents an approach for Evoked Expressions from Videos (EEV) challenge, which aims to predict evoked facial expressions from video. We take advantage of pre-trained mod…
The 1st Agriculture-Vision Challenge: Methods and Results
Mang Tik Chiu, Xingqian Xu, Kai Wang +39
The first Agriculture-Vision Challenge aims to encourage research in developing novel and effective algorithms for agricultural pattern recognition from aerial images, especially f…
Eye Semantic Segmentation with a Lightweight Model
Van Thong Huynh, Soo-Hyung Kim, Guee-Sang Lee +1
In this paper, we present a multi-class eye segmentation method that can run the hardware limitations for real-time inference. Our approach includes three major stages: get a grays…
