Professor Jong-Seok Lee's research lab specializes in advanced materials and systems for environmental and biomedical applications, with a strong focus on adsorption science, particularly CO2 capture using zeolites and composite materials. The lab also explores perceptual video compression and scalable video coding to enhance quality of experience in multimedia communications. Additionally, it investigates molecular mechanisms in neuroinflammation, especially the role of transcription factors and caspases in microglial cell death. The lab integrates experimental, computational, and perceptual modeling approaches to address challenges in energy efficiency, healthcare technology, and next-generation data delivery.

This paper presents a foveated coding method using audio-visual focus of attention and its evaluation through extensive subjective experiments on both standard-definition and high-definition sequences. Regarding a sound-emitting region as the location drawing the human attention, the method applies varying quality levels in an image frame according to the distance of a pixel to the identified sound source. Two experiments are presented to prove the efficiency of the method. Experiment 1 examines
