Research

Topic-wise, one of my recurring interests is on the analysis and synthesis of repetitive phenomena such as textures, samples, noises, structures, motions, and interactions. These can involve various fields including computer graphics, parallel computing, and human computer interaction. In fact, since computer science is about repetitive computations, I have excuses to work on whatever I like.
Methodology-wise, I am mainly interested in developing fundamental algorithms that span diverse phenomena driven by practical applications. I like to observe prevailing issues in the human side of computation (e.g. graphics and HCI), and figure out the underlying problems and core solutions.
Note: due to obvious reasons I cannot release the code for almost all projects I did with Microsoft. If the code is available, I will put it online here. I am afraid I do not have time to answer every email regarding source codes.

SIGGRAPH Asia 2010
[paper][supplement][video (youtube)][video (avi)][exe demo][spectrum analysis code]
The sampling part is an extension of my SIGGRAPH 2008 paper, but the analysis part is novel in the use of spectral mesh basis instead of Fourier basis to compute spectrums. (And yes, I like to make a lot of noises.)

SIGT Anisotropic Blue Noise Sampling
Hongwei Li, Li-Yi Wei, Pedro V. Sander, Chi-Wing Fu
SIGGRAPH Asia 2010

AT Motion Field Texture Synthesis
Chongyang Ma, Li-Yi Wei, Baining Guo, Kun Zhou
SIGGRAPH Asia 2009
[paper][video (youtube)]
This is my first animation paper. I never thought I am going to have a paper related to fluids, but since Chongyang (with a background in physics) told me that is where his passion is, I tried to come up with an idea that could combine his interest and my expertise. (Attempting to accommodate students' wishes seems to be a good way to force me learn new things.) For this project I picked up fluids from scratch, and I have benefited tremendously from the course notes by Müller-Fischer and Bridson.

T State of the Art in Example-based Texture Synthesis
Li-Yi Wei, Sylvain Lefebvre, Vivek Kwatra, Greg Turk

PSRT Parallel Poisson Disk Sampling
Li-Yi Wei
SIGGRAPH 2008
[paper][video (youtube)][video (zip)][talk][code (MS only)][exe (siga10)]
I wrote the paper from a sampling point of view, but at my presentation I motivated the problem as a new potential methodology for parallelizing algorithms. You might want to check out my talk slides as this new information is not in the official paper. Note: if you can't access the MS-only code, you can use the public domain exe from my SIGGRAPH Asia 2010 paper on surface sampling and treat the planar domain here as a special case.

PSRT Parallel White Noise Generation on a GPU via Cryptographic Hash
Stanley Tzeng, Li-Yi Wei
SIGGRAPH Symposium on Interactive 3D Graphics and Games 2008
[paper][video (youtube)][video (avi)][talk][code (Cg, MS only)][code (CUDA, public)]
This is a technique that generates uniform random numbers in a totally parallel and random-accessible fashion. The basic idea is very simple: given an input that can be trivially produced in parallel (e.g. a linear ramp), use cryptographic hash to scramble the individual samples independently and in parallel, and the output set will exhibit white noise statistics. I came up this idea around year 2004 (while studying cryptography as a hobby), but couldn't really implemented the thing until commodity GPUs support integer shader arithmetic.

ITU High Dynamic Range Image Hallucination
Lvdi Wang, Li-Yi Wei, Kun Zhou, Baining Guo, Heung-Yeung Shum
EUROGRAPHICS Symposium on Rendering 2007
[paper][video (youtube)][video (avi)][talk][code (MS only)]
A certain attendee during a certain SIGGRAPH conference commented to me that "he really had enough for all these HDR and texture synthesis papers". This paper is a combination of these two.

Jianye Lu, Athinodoros S. Georghiades, Andreas Glaser, Hongzhi Wu, Li-Yi Wei, Baining Guo, Julie Dorsey, Holly Rushmeier
ACM Transactions on Graphics, Volume 26, Issue 1 (January 2007)
This is a collaboration between Yale and MSRA. This is how we divided our job: Yale people did all the hard work (capturing, analysis, and paper writing) and MSRA people did all the fun work (texture synthesis and rendering). I liked this deal a lot and I am looking forward for future collaborations.

AO Visualizing Flow Fields by Perceptual Motion
Li-Yi Wei
Microsoft Research Technical Report MSR-TR-2006-82 June 2006
[paper]
Some little experiments showing that a static picture can produce animation sensations. Human perception is treacherous. You might also want to check out a related paper in SIGGRAPH 2008: "Self-Animating Images: Illusory Motion Using Repeated Asymmetric Patterns".

RP Multi-Layer Depth Peeling via Fragment Sort
Baoquan Liu, Li-Yi Wei, Ying-Qing Xu
Microsoft Research Technical Report MSR-TR-2006-81 June 2006 (later published in CAD/Graphics '09)
[paper]
I know reading and writing the same frame-buffer-object within the same rendering pass is hazardous, but I couldn't avoid my desire to abuse it. So I presented this little naughty trick to peel 8 layers of fragments per rendering pass. The k-buffer paper continued this abuse, and also started some interesting ideas on programmable ROP (which I believe will become reality in near generation GPUs).

T Fast Example-based Surface Texture Synthesis via Discrete Optimization
Jianwei Han, Kun Zhou, Li-Yi Wei, Minmin Gong, Hujun Bao, Xinming Zhang, Baining Guo
The Visual Computer (Pacific Graphics 2006)
[paper][video (youtube)][video (avi)][talk][code (MS only)]
The key result of this paper is animated texture flows on arbitrary surfaces. This cannot be adequately shown by static images (or even animated gifs), so it is best to take a look at our video. Our key algorithm is a discrete solver, combining texture optimization with k-coherence. I believe this achieves the best quality/performance tradeoff among existing techniques. Furthermore, it is amenable for GPU implementation.

RP Silhouette Texture
Hongzhi Wu, Li-Yi Wei, Xi Wang, Baining Guo
EUROGRAPHICS Symposium on Rendering 2006

This paper is totally Hongzhi's idea, and I just help him polish and write the paper. Hongzhi was only an undergrad while working on this paper.

RP Real-time Multi-perspective Rendering on Graphics Hardware
Xianyou Hou, Li-Yi Wei, Heung-Yeung Shum, Baining Guo
EUROGRAPHICS Symposium on Rendering 2006
[paper][video (youtube)][video (mov)][talk]
I started to believe that polygon rasterization can be used to render secondary rays as well. See my "Nonlinear Beam Tracing" paper for the second foray.

G Subspace Gradient Domain Mesh Deformation

They offered me free book copies, so I thought it is worth the little work of porting my Graphics Hardware 2004 paper into a book chapter.

RPT Tile-based Texture Mapping on Graphics Hardware
Li-Yi Wei
SIGGRAPH/EUROGRAPHICS Conference on Graphics Hardware 2004
My only paper with NVIDIA. I did it primarily to escape from the routines of my GPU architecture day job. The unofficial record is that I am the first NVIDIAN who ever published a paper totally unrelated to the main job functions.

TP Order-Independent Texture Synthesis

This is my first publication. Even though much less well known than my SIGGRAPH 2000 paper it serves an important historical evidence, proving that my TSVQ algorithm was derived from [Popat and Picard 1993], not [Efros and Leung 1999] (which is a great paper; don't get me wrong).
