We present a novel process for acquiring detailed facial geometry with high resolution diffuse and specular photometric information from multiple viewpoints using polarized spherical gradient illumination. Key to our method is a new pair of linearly polarized lighting patterns which enables <i>multiview</i> diffuse-specular separation under a given(More)
We present a novel technique for acquiring detailed facial geometry of a dynamic performance using extended spherical gradient illumination. Key to our method is a new algorithm for <i>jointly</i> aligning two photographs, under a gradient illumination condition and its complement, to a full-on tracking frame, providing dense temporal correspondences under(More)
<b>Overview</b> In 2008, the "Digital Emily" project [Alexander et al. 2009] showed how a set of high-resolution facial expressions scanned in a light stage could be rigged into a real-time photoreal digital character and driven with video-based facial animation techniques. However, Digital Emily was rendered offline, involved just the front of the face,(More)
We present a set of algorithms and an associated display system capable of producing correctly rendered eye contact between a three-dimensionally transmitted remote participant and a group of observers in a 3D teleconferencing system. The participant's face is scanned in 3D at 30Hz and transmitted in real time to an autostereoscopic horizontal-parallax 3D(More)
We present a novel technique for acquiring the geometry and spatially-varying reflectance properties of 3D objects by observing them under continuous spherical harmonic illumination conditions. The technique is general enough to characterize either entirely specular or entirely diffuse materials, or any varying combination across the surface of the object.(More)
We demonstrate a novel light probe which can estimate the full dynamic range of a scene with multiple bright light sources. It places diffuse strips between mirrored spherical quadrants, effectively co-locating diffuse and mirrored probes to record the full dynamic range of illumination in a single exposure. From this image, we estimate the intensity of(More)
Current scanning techniques record facial <i>mesostructure</i> with sub-millimeter precision showing pores, wrinkles, and creases. However, surface roughness continues to shape specular reflection at the level of <i>microstructure</i>: micron scale structures. Here, we present an approach to increase the resolution of mesostructure-level facial scans using(More)
Video projectors are rapidly shrinking in size, power consumption, and cost. Such projectors provide unprecedented flexibility to stack, arrange, and aim pixels without the need for moving parts. We present a dense projector display that is optimized in size and resolution to display an autostereoscopic life-sized 3D human face with a wide 110 degree field(More)
Head-mounted cameras are an increasingly important tool for capturing an actor's facial performance. Such cameras provide a fixed, unoccluded view of the face. The resulting imagery is useful for observing motion capture dots or as input to existing video analysis techniques. Unfortunately current systems are typically affected by ambient light and(More)
We present a technique for achieving tracked vertical parallax for multiple users using a variety of autostereoscopic projector array setups, including frontand rear-projection and curved display surfaces. This hybrid parallax approach allows for immediate horizontal parallax as viewers move left and right and tracked parallax as they move up and down,(More)
