We have developed a visual perception model illustrating resolution and contrast sensitivity variation across retinal eccentricities using multi-layer frequency analysis. We have also studied visual perception models with blind field to reveal how blind field in human perception is invisible. Content-aware image resizing has been applied to our perception model as scotoma carving and scotoma replacement. In addition, we also model temporal visual perception of retinal stimulation to illustrate important vision dynamics and its effect. We have also worked on image enhancement to improve object recognition considering human visual perception model.

Recently, we have studied visual perception with AR displays considering binocular vision (monocular/binocular rivalry, depth perception, and eye movements). As expansion, we are currently studying roles of double vision in binocular visual perception.
