Kenji Koyano
Research Interests
Dr. Koyano received his PhD from the University of Tokyo. He is interested in the visual perception processing: how visual features are analyzed, how those features are integrated and come up to our conscious mind. Now we are trying to show how physically same visual stimuli could be recognized differently after learning, using face-perception systems as a model.
