Off-Manifold Refinement: Guiding Video Generators with a Frozen World Model
Hai Nguyen-Truong, Tuan-Anh Vu, Dang Huynh
Modern video generators routinely fail at physical dynamics: objects float, trajectories violate gravity, contacts vanish. Standard denoising and flow-matching objectives fit visua…
Cross4D-JEPA: Dense Cross-modal Correspondence Distillation for 4D Point Cloud Representation Learning
Trung Thanh Nguyen, Hai Nguyen-Truong, Tu Vo +2
Automatic understanding of dynamic 4D point clouds, the 3D-point sequences captured over time by depth sensors and LiDAR, is central to robotics and embodied perception. Yet annota…
How You Move Tells What You'll Do: Trajectory-Conditioned Egocentric Prediction
Sejoon Jun, Hai Nguyen-Truong, Luigi Seminara +1
Predicting how a person's first-person view will evolve (what action will follow, what plan completes a task, whether an in-progress shot will score) is fundamentally under-specifi…
Semantic Alignment in Hyperbolic Space for Open-Vocabulary Semantic Segmentation
Hoang M. Truong, Hai Nguyen-Truong, Dang Huynh
Open-vocabulary semantic segmentation requires adapting image-level vision-language models such as CLIP to dense pixel-level prediction, which is challenging due to the mismatch be…
Toward an Artificial General Teacher: Procedural Geometry Data Generation and Visual Grounding with Vision-Language Models
Hai Nguyen-Truong, Alper Balbay, Tunga Bayrak
We study visual explanation in geometry education as a Referring Image Segmentation (RIS) problem: given a diagram and a natural language description, the task is to produce a pixe…
Power of Boundary and Reflection: Semantic Transparent Object Segmentation using Pyramid Vision Transformer with Transparent Cues
Tuan-Anh Vu, Hai Nguyen-Truong, Ziqiang Zheng +4
Glass is a prevalent material among solid objects in everyday life, yet segmentation methods struggle to distinguish it from opaque materials due to its transparency and reflection…
Vision-Aware Text Features in Referring Image Segmentation: From Object Understanding to Context Understanding
Hai Nguyen-Truong, E-Ro Nguyen, Tuan-Anh Vu +3
Referring image segmentation is a challenging task that involves generating pixel-wise segmentation masks based on natural language descriptions. The complexity of this task increa…
The 2nd Workshop on Maritime Computer Vision (MaCVi) 2024
Benjamin Kiefer, Lojze Žust, Matej Kristan +46
The 2nd Workshop on Maritime Computer Vision (MaCVi) 2024 addresses maritime computer vision for Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicles (USV). Three challenge…
MarineVRS: Marine Video Retrieval System with Explainability via Semantic Understanding
Tan-Sang Ha, Hai Nguyen-Truong, Tuan-Anh Vu +1
Building a video retrieval system that is robust and reliable, especially for the marine environment, is a challenging task due to several factors such as dealing with massive amou…
1st Workshop on Maritime Computer Vision (MaCVi) 2023: Challenge Results
Benjamin Kiefer, Matej Kristan, Janez Perš +70
The 1 Workshop on Maritime Computer Vision (MaCVi) 2023 focused on maritime computer vision for Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicle (USV), and…
SegTransVAE: Hybrid CNN -- Transformer with Regularization for medical image segmentation
Quan-Dung Pham, Hai Nguyen-Truong, Nam Nguyen Phuong +1
Current research on deep learning for medical image segmentation exposes their limitations in learning either global semantic information or local contextual information. To tackle…
