Our research is aimed at developing computational models for understanding of the visual mechanisms and the application in computer vision. The research interests include:

Image Restoration and Enhancement: To develop a computational models based on the mechanisms of retina, LGN and V1 neurons and the applications in image denoising, dehazing, enhancement, color constancy, etc.

Image Segmentation: Computational models of image segmentation, contour detection, salient object detection, etc., inspired by corresponding mechanisms in primary visual cortex

Computational Neurosicence: Computational neural mechanism of visual system, perceptual decision making and working memory. Focus on multiple-choice decision making, the neural circuit for value-based decision making, and the information encoding in primary visual cortex.
