Seeing the assets along our roads
A road-asset detector combines a pretrained Vision Transformer with YOLOX and a feature-pyramid decoder. The study evaluates detection on Thai highway imagery, including small roadside objects such as kilometer stones.
Learning from highway crash records
This study transforms discrete crash features into grayscale images using Weight of Evidence, then trains a VGG-based neural network to classify accident severity. It uses Thai highway crash records from 2011–2023.
Mapping buildings with GeoSAM
Researchers applied GeoSAM to extract building footprints from UAV true orthophotos with a 5 cm ground sampling distance. The study covers science and engineering areas at Chulalongkorn University.
Finding text in complex scenes
A convolutional network predicts text, offset and border masks to locate curved and closely spaced text. Polygon offsetting and border augmentation help separate neighboring text instances in natural images.
Road safety & transport
Understanding road risk, travel behaviour and network performance through safety assessment, traffic information and transport research.
Pavements & asset management
Connecting pavement condition, material performance and life-cycle costs to maintenance planning and infrastructure decisions.
Geospatial information & surveying
Developing knowledge and tools around geographic information systems, surveying and infrastructure information management.
Disaster information & resilience
Studying how information supports decisions during disasters, alongside knowledge exchange on preparedness and response.
Initiative · AI for Physical Sciences
AI Foundation Models for Civil Infrastructure
Integrating computer vision, foundation models, and statistical learning into large-scale civil engineering systems. Our initiatives focus on automated satellite segmentation, real-time roadside asset intelligence, probabilistic highway safety modeling, and low-distortion geodetic coordinate transformations — backed by open code and reproducible benchmarks.

Compares four ways to interpret down-hole seismic measurements at three Thai sites, examining how overburden pressure affects inferred soil velocities.
Conformal Prediction for Uncertainty Quantification and Reliable HER2 Status Classification in Breast Cancer IHC Images
IEEE Access, 13, pp. 51645–51659
Research focus
Studies conformal prediction for quantifying uncertainty in HER2 status classification from breast-cancer immunohistochemistry images.
Crash severity prediction using a virtual geometry-group-based deep learning approach with images-based feature representation
Results in Engineering, 27, 106155
Research focus
A VGG-based convolutional model predicts crash severity from Thai highway records for 2011–2023. Categorical features become grayscale images, with class balancing and Bayesian optimisation; evaluation uses F1-score and AUC.
