Focal Pre-Correction of Projected Image for Deblurring Screen Image
We propose a method for reducing out-of-focus blur caused by projector projection. In this method, we estimate the Point-Spread-Function (PSF) of the out-of-focus blur in the imag...

Interaction of ON and OFF pathways for visual contrast measurement
We propose a novel model of visual contrast measurement based on segregated ON and OFF pathways. Two driving forces have shaped our investigation: (1) establishing a mechanism sele...
