As the snow thaws, the VCL welcomes the following new students to the lab. Several join us from around the globe!
VCL member Annie Dai successfully defended her master’s thesis, titled “Computational Fabrication – String Art.” Her thesis proposed a technique for creating realistic string art, a form of artwork where artists wind strings around pins, from a reference image.
CS Professor Wojciech Jarosz has received an NSF CAREER Award! The NSF Program “offers the National Science Foundation’s most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research.”
A new study led by Gurprit Singh of Dartmouth’s Visual Computing Lab presents an in-depth exploration of sampling strategies commonly used to create computer-generated images. This research highlights some previously unknown strengths and weaknesses of those strategies, and proposes a few simple tricks to tame their weaknesses.
A new study co-authored by Visual Computing Lab Director Wojciech Jarosz builds on his previous work simulating how light is scattered, refracted, and reflected. Rather than assume the speed of light is infinite, as one usually would in computer graphics, this work incorporates the true speed of light in order to visualize how the light bounces around a scene filled with particles and surfaces.
VCL student Xi Deng successfully defended her master’s thesis, titled “Photon Surfaces: Render Volume Robustly with Unbiased Density Estimators,” bright and early on a Friday morning. Her work continued a thread of research from Dartmouth’s Visual Computing Lab on techniques for simulating complex particle-based materials such as fog, clouds, fire, smoke, and stained glass.
Fresh research from Dartmouth’s Visual Computing Lab demonstrates how augmented reality could be used to help people with reduced vision read signs in their environment. The team not only designed an application able to detect and display enhanced text via Microsoft’s HoloLens, they conducted a behavioral experiment to validate their system’s effectiveness.
A new theory based on the physics of cloud formation and neutron scattering could help animators create more lifelike movies, according to a Dartmouth-led study. Software developed using the technique focuses on how light interacts with microscopic particles to develop computer-generated images.
Xiaoting Zhang joins VCL as a postdoc with Professor Whiting.
Prof. Wojciech Jarosz, together with Romain Prévost (ETH Zurich/Disney Research Zurich), Alec Jacobson (ETH Zurich/Columbia University), and Olga Sorkin-Hornung (ETH Zurich) have developed a computationally-assisted spray painting system that allows novices to spray paint accurate reproductions of photographs as large murals. The research appears in April's issue of the journal Computers & Graphics.
Congratulations to Liane Makatura! She is among eight undergraduate students selected internationally to win the Adobe Research Women-in-Technology Scholarship.
Members of VCL attended the Symposium on Computational Fabrication, held at MIT this week. PhD student Athina Panotopoulou presented in the poster session, highlighting recent work on Perceptual Models of Preference in 3D Printing Direction.
The Daily Mail reports on a new analysis by Srivamshi Pittala, Emily Whiting and Hany Farid that confirms the authenticity of the famous backyard photo of Lee Harvey Oswald. See the whole article at the Daily Mail.
Research lead by VCL's Prof. Jarosz in collaboration with Disney Research was presented at Pacific Graphics 2015 last week, where it won the Best Paper Award. The paper describes a novel method for projecting color images using a white light source and an optical device with no colored components—consisting solely of one or two prisms and two masks printed on transparencies.

Introducing a new MS Degree in CS with a concentration in Digital Arts Program at Dartmouth College!
Prof. Emily Whiting was awarded an NSF Grant for her work in Structurally-Aware Computation for Geometry Acquisition and Design. The award program is under the Directorate for Computer and Information Science and Engineering (CISE): Research Initiation Initiative (CRII).
Welcome to the brand new home of the Dartmouth Visual Computing Lab!
We describe a photo forensic technique based on detecting inconsistencies in lighting. This technique explicitly measures the 3-D lighting properties for individual people, objects, or surfaces in a single image. We show that with minimal training, an analyst can accurately specify 3-D shape in a single image from which 3-D lighting can be automatically estimated. A perturbation analysis on the estimated lighting is performed to yield a probabilistic measure of the location of the illuminating light. Inconsistencies in lighting within an image evidence photo tampering.
Professors Emily Whiting and Wojciech Jarosz will both be serving on the SIGGRAPH 2015 technical papers committee.
Emily Whiting presented at TEDx Beacon Street on 3D printing -- the physics of objects.
