Wenjin Zhou, a first year Ph.D. student in computer science, received the first place award in the Association for Computing Machinery’s (ACM) Student Research Competition at the 2006 SIGGRAPH conference. Her award winning presentation, Perceptual Coloring and 2-D Sketching for Segmentation of Neural Pathways, utilizes scientific visualization to help doctors understand and analyze white matter structures within the human brain. Zhou, along with co-authors Peter G. Sibley, Song Zhang, David F. Tate, and David H. Laidlaw have developed BrainApp, an application to visualize the geometric disparity between white matter tracts obtained from DT-MRI data by coloring in perceptually ...

"Predicting 3D People from 2D Pictures" co-authored by Ph.D. candidate Leonid Sigal and Professor Michael Black, won the best paper award at the Forth International Conference on Articulated Motion and Deformable Objects (AMDO-e 2006) in Mallorca, Spain.

Sigal's research focuses on building vision systems that can detect and track people in images and video. Such vision systems have many applications in the entertainment industry, rehabilitation medicine, surveillance and robotics. Black and Sigal’s latest work uses statistical models and a novel hierarchical probabilistic framework to infer the 3-dimensional pose of a person from a single image ...

Ph.D. candidate Dan Keefe’s work is featured on the ACM SIGGRAPH ARTS website as part of the Established Artist Introduces Emerging Artist (EA2) series. The article highlights Dan’s work with CavePainting, an artistic medium that uses a 3D analog of 2D brush strokes to create 3D works of art in an immersive virtual reality environment. Dan’s research with Brown’s Center for Advanced Scientific Computation and Visualization focuses on developing software to enable freehand drawing within the environment of the Cave - an eight-foot cubicle in which high-resolution stereo graphics are projected onto three walls and the ...
