How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Conference Paper
Automultiscopic 3D displays allow a large number of viewers to experience 3D content simultaneously without the hassle of special glasses or head gear. Our display uses a dense array of video projectors to generate many images with high-angular density over a wide-field of view. As each user moves around the display, their eyes smoothly transition...
Article
We present a technique for synthesizing the effects of skin microstructure deformation by anisotropically convolving a high-resolution displacement map to match normal distribution changes in measured skin samples. We use a 10-micron resolution scanning technique to measure several in vivo skin samples as they are stretched and compressed in differ...
Article
We endeavor to model dynamic microfacet distributions of rough surfaces such as skin to simulate the changes in surface BRDF under stretching and compression. We begin by measuring microfacet distributions at 5-micron scale of several surface patches under controlled deformation. Generally speaking, rough surfaces become flatter and thus shinier as...
Article
We present a technique for achieving tracked vertical parallax for multiple users using a variety of autostereoscopic projector array setups, including front- and 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...

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 degr...

We present a technique for creating realistic facial animation from a set of high-resolution static scans of an actor's face driven by passive video of the actor from one or more viewpoints. We capture high-resolution static geometry using multi-view stereo and gradient-based photometric stereo [Ghosh et al. 2011]. The scan set includes around 30 e...

We propose a system that enables the display of multiplex-hidden images for selected users with highly accessible polarizing filters. This system requires no electronic devices for users. It is designed with high dynamic range (HDR) projection technology and realizes the display of multiplexed content with HDR. Recently, research into HDR projectio...

We have enabled the superimposition of multiplexed images on the same screen at the same time with tangible and stable equipment. Our multiplex images can be seen by wearing special configured polarized glasses, and the image projection method is designed to be based on current 3D stereoscopic technology, which is now prevalent and making rapid pro...
