We describe a theoretical framework for reversibly modulating 4D light fields using an attenuating
mask in the optical path of a lens based camera. Based on this framework, we present …

We show a new camera based interaction solution where an ordinary camera can detect
small optical tags from a relatively large distance. Current optical tags, such as barcodes, must …

We introduce an interactive, portable, and inexpensive solution for estimating refractive errors
in the human eye. While expensive optical devices for automatic estimation of refractive …

In this article, we develop tools for shadow modification in images where a shadowed
region is characterized by soft boundaries with varying sharpness along the shadow edges. …

We advocate the use of quickly‐adjustable, computer‐controlled color spectra in photography,
lighting and displays. We present an optical relay system that allows mechanical or …

We present an algorithm to automatically estimate three-dimensional light positions from an
unordered set of images. We collect images using a single stationary camera while …

A treatment with projected light for Mark Rothko's Harvard Murals (1962) is proposed. The
group of five paintings on canvas has changed color due to the presence of a fugitive red …

We apply simplified image-based lighting methods to reduce the equipment, cost, time, and
specialized skills required for high-quality photographic lighting of desktop-sized static …

We propose a novel wide angle imaging system inspired by compound eyes of animals.
Instead of using a single lens, well compensated for aberration, we used a number of simple …

The asymptotic analysis of a class of stochastic partial differential equations (SPDEs) with
fully local monotone coefficients covering a large variety of physical systems, a wide class of …
