A Headlight that Sees through Rain and Snow
The goal is to build a smart vehicular headlight that can reduce visibility of rain and snow, making it less stressful and more safe for us to drive at night.
Structured light 3D under Global Illumination
The goal is to recover 3D shapes of complex objects using structured lighting that is robust to interreflections, sub-surface scattering and defocus.
Structured Light in Sunlight
We have built a structured light sensor for 3D reconstruction that works in sunlight using an off-the-shelf low-power laser projector.
Multi-layered Display with Water drops
By using precisely controlled valves and a projector-camera system, we create a vibrant, multi-layered water drop display. The display can show static or dynamically generated images on each layer, such as text, videos, or even interactive games.
Display with Water drops
We design a Projector-Camera system for creating a display with water drops that form planar and curved screens.
(De)Focused Illumination and Global Light Transport
Our goal is to recover scene properties in the presence of global illumination. To this end, we study the interplay between global illumination and the depth cue of illumination defocus.
Temporal Dithering of Illumination
We present a framework for fast active vision using Digital Light Processing (DLP) projectors.
Ground Shadow Detector
We have developed a detector to identify shadow boundaries on the ground in low quality consumer photographs.
Webcam clipart
We introduce a new, high-quality dataset of calibrated time-lapse sequences. Illumination conditions are estimated in a physically-consistent way and HDR environment maps are generated for each image.
Illumination from a single outdoor image
Given a single outdoor image, we present a method for estimating the likely illumination conditions of the scene.
What do the sun and sky tell us about the camera?
We analyze two sources of information available within the visible portion of the sky region: the sun position, and the sky appearance.
