Interests

My research interests include multimedia data transmission and Quality of Experience (QoE), mesh simplification and Levels-of-Detail, 3DTV, 3D textured mesh visualization, image processing and adaptive learning/assessment. I introduced the concept of Just-Noticeable-Difference (JND) and Relative Change on 3D TexMesh in the scale-space domain - validated following psychophysical two-alternative-choice methodology.

Summary

My research focus is on the analysis of multimedia patterns and their human perceptual impacts on real-world applications, e.g., animation, education, surveillance and healthcare. My techniques are built upon mathematical formulations like Random-Walks, Set Partitioning in Hierarchical Tree (SPIHT), Conditional Random Field (CRF), Scale-Space Filtering and Just-Noticeable-Difference (JND). Projects include: Improved automatic multi-exposure image fusion and correspondence; introduced perceptually enhanced techniques for automatic segmentation using visual cues and for enhancing medical or photographic image quality; motion capture data compression and transmission; multi-object tracking. The Computer Reinforced Online Multimedia Education (CROME) framework, which focused on adaptive learning/assessment, was designed and prototyped during the period from 2006-2012. More recent research is focused on Intelligent Analysis of Signal Decomposition and Aggregation in different application domains, which include satellite signal (InSAR) filtering and coherence estimation, LiDAR point cloud modelling, Parkinson's Disease progress tracking, vital sign pattern recognition and pressure injury monitoring.
