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…
