HoloChat: 3D Avatars on Mobile Light Field Displays
Emerging Technologies at SIGGRAPH 2015
Holographic displays have long inspired science fiction writers and movie makers as the communication platform of the future. Why should we restrict ourselves to a two-dimensional screen if we can transmit our virtual selves in 3D? We demonstrate the first mobile holographic communication system through performance-driven digital avatars.
Chromatic Calibration of an HDR Display using 3D Octree Forests
Accepted to ICIP 2015, best top 10% Paper!
We present a method for HDR display calibration that takes into account the variation of the chrominance error over luminance. We propose a data structure for enabling efficient representation and querying of the calibration function, which also allows user guided balancing between memory consumption and the amount of computation.
Dynamic Mapping for Multiview Autostereoscopic Displays
Publication Page [ PDF ]
We introduce a method for driving multi-view displays, dynamically assigning views to hardware display zones, based on potentially multiple observer's current head positions. Rather than using a static one-to-one mapping of views to zones, the mapping is updated in real time. Quantitative and visual evaluation demonstrates that this method substantially reduces crosstalk.
RELight - Captures incredibly detailed surface texture allows for retroactive relighting for unique viewing experience
The Relightable Dome is a device we designed for capturing RTI images. Basically it automatically captures images with different lighting conditions.
This is a project sponsored by NSF I-Corps program.

3D+2D TV: 3D Displays with No Ghosting for Viewers Without Glasses
This paper is presented at SIGGRAPH 2013 in Los Angeles.
In this project, we demonstrate a simple method that provides viewers with glasses a 3D experience, while viewers without glasses see a 2D image without artifacts. Project Page
An Autostereoscopic Projector Array Optimized for 3D Facial Display
This paper is published on Journal of Electronic Imaging 2014.
The prototype is presented at SIGGRAPH 2013 E-Tech
This is a dense projector display that is optimized in size and resolution to display a glasses-free life-sized 3D human face with a wide 110 degree field of view.
When Does the Hidden Butterfly Not Flicker?
This paper is accepted to SIGGRAPH Asia 2014 - Tech Brief Program.
The emergence of high frame rate computational displays created opportunities for viewing experiences impossible on traditional displays. However, commonly accepted standards might no longer apply to these new displays. For example, under what conditions do viewers no longer perceive flicker? Project Page
FlexISP: A Flexible Camera Image Processing Framework
Accepted to SIGGRAPH Asia 2014
Our end-to-end system reconstructs images and jointly accounts for demosaicking, denoising, deconvolution, and missing data reconstruction. Thanks to the separation of image model and formulation based on natural-image priors, we support both conventional and unconventional sensor designs.
