In this paper, we propose a method for determining the vignetting function given only a single image. Our method is designed to handle both textured and untextured regions in orde...
In this paper, we propose a method for estimating the
optical center of a camera given only a single image with
vignetting. This is accomplished by identifying the center
of the...

In this paper, we present a novel single-image vignetting method based on the symmetric distribution of the radial gradient (RG). The radial gradient is the image gradient along t...

Estimating the reflectance and illumination from a single image becomes particularly challenging when the object surface consists of multiple materials. The key difficulty lies ...
Camera spectral sensitivity plays an important role for various color-based computer vision tasks. Although several methods have been proposed to estimate it, their applicability ...
