Estimation of Multiple Illuminants from a Single Image of Arbitrary Known Geometry
We present a new method for the detection and estimation of multiple illuminants, using one image of any object with known geometry and Lambertian reflectance. Our method obviates ...

Advice Coins for Classical and Quantum Computation
We study the power of classical and quantum algorithms equipped with nonuniform advice, in the form of a coin whose bias encodes useful information. This question takes on particu...

Hardware acceleration of iterative image reconstruction for X-ray computed tomography
X-ray computed tomography (CT) images could be improved using iterative image reconstruction if the 3D conebeam forward- and back-projection computations can be accelerated signif...

Color Constancy using 3D Scene Geometry
The aim of color constancy is to remove the effect of the color of the light source. As color constancy is inherently an ill-posed problem, most of the existing color constancy ...
