Research Directions


It is essential to adopt human-centric approach to our studies to meet increasing demands from the industry and the ageing society. Bearing this in mind, our research includes, but is not limited to, the following areas:

 

Color in lighting


  • Methods of measuring visual perception of light sources
  • LED lighting design for interior and exterior spaces
  • Special LED light sources for improving work performance and health enhancing
  • Developing LED light sources of high color rendition and energy saving

 

Color and imaging


  • High dynamic range imaging and its color management techniques
  • Methods of visual assessment of image quality for 2D and 3D images
  • Developing psychophysical models of image quality for 2D and 3D images
  • Influences of 3D images on health and security
  • Developing systems for accurate appearance simulation
  • Imaging techniques for new areas such as digital archiving, skin care and cosmetics
  • Multi-angle imaging system

 

Appearance measurement


  • Total appearance system for various object sizes observed by various age groups in scotopic and mesopic viewing conditions
  • Color vision and appearance models for 2D and 3D images that are either static or dynamic
  • Methods of measuring total appearance including color, gloss, transparency, translucency and texture
  • Developing models of color emotion and color harmony for various applications
  • 3D-printing-integrated color appearance reproduction, including highly accurate simulation of color appearance of objects, standard material data development and object appearance reproduction

 

We are also developing highly potential products, including:
  • Display systems for enhancing image quality such as TV displays, mobile devices, projectors and e-books
  • Measuring and simulation systems for appearance of 2D or 3D objects, including color, gloss, transparency, translucency and texture
  • Psychophysical analysis systems for lighting based on short-term and long-term data for various lit environments
  • Affective lighting systems for enhancing the user’s emotion and work performance
  • Lighting and display systems for older people and people with low vision
  • Applications of medical imaging for enhancing color reproduction
  • High-speed and high-precision 3D scanning system that provides a faster and simpler approach to collection of 3D data for highly customizable products and data analysis for areas such as customized shoes, 3D online testing and digital dentists
