Research Interest
My research mainly focuses on the mechanism of human colour vision. I am particularly interested in how our visual system recognizes a scene illuminant and subtract its influence to identify objects under different illuminants. What kind of cues in a scene do we utilize to estimate an illuminant color? How well can we separate components that belong to an illuminant and an object? What illuminant and object properties affect the performance? Can dynamic cues facilitate the object identification?
My research aims to address these questions based on psychophysical experiment with carefully controlled computer-generated visual stimuli.
