Welcome to GrUVi @ CS.SFU!

We are an inter-disciplinary team of researchers working in visual computing, in particular, computer graphics and computer vision. Current areas of focus include 3D and robotic vision, 3D printing and content creation, animation, AR/VR, geometric and image-based modelling, machine learning, natural phenomenon, and shape analysis. Our research works frequently appear in top venues such as SIGGRAPH, CVPR, and ICCV (we rank #11 in the world in terms of top publications in visual computing, as of 5/2019) and we collaborate widely with the industry and academia (e.g., Adobe Research, Google, MSRA, Princeton, Stanford, and Washington). Our faculty and students have won numerous honours and awards, including FRSC, Alain Fournier Best Thesis Award, Google Faculty Award, TR35@Singapore, NSERC Discovery Accelerator, and six best paper awards from ECCV, SCA, SGP, etc. Gruvi alumni went on to take up faculty positions in Canada, the US, and Asia, while others now work at companies including Apple, EA, Facebook, Google, IBM, and Microsoft.

Kangxue Yin wins an Award!

May 23, 2019

The GrUVi team congratulates Kangxue Yin, whom received the prestigious Chinese Government Award for Outstanding Self-financed Students Abroad!

This award was established in 2003 by the China Scholarship Council. The worldwide recipients are chosen annually based on a record of outstanding accomplishments in any discipline.

This award is considered the highest award given by Chinese government for Chinese graduate students studying abroad who do not receive regular financial support from Chinese government.

Currently, this award is granted to only 500 students every year. Since there are around half a million Chinese students to study abroad per year, this a highly competitive award. For the academic year 2018, only 6 awardees were based in British Columbia, Canada. Among them, Kangxue was the only student majoring in Computer Science.

× New and Returning GRuVIers!

April 14, 2019

The GrUVi team would like to welcome three SFU undergrad students who are joining the lab for summer/visiting research:

  • Leo Li - to start in the summer as a VPA USRA working on representation learning;
  • Atticus Shi - who is working on a geometric optimization problem related to fixture design for CNC machining;
  • Azmarie Wang - to start in the summer as a special project student working on creative design problems.

In addition, Xiaogang Wang is joining us as a visiting PhD from Beihang University, the same university as Jiongchao. He comes with an already impressive research record (one SIG Asia and one CVPR), working with Kevin, a GrUVi alumni himself.

Fenggen (Fogg) Yu, will be a new PhD starting this fall. Fenggen is from Nanjing University and he had already collaborated with GrUVi members on a ACM TOG paper. He also has a CVPR paper this year.

We are also pleased to announce that two current members of the lab, Zhiqin and Jon, will continue as PhD students this fall.

Finally, Akshay is returning from his internship at Amazon (Israel) and Manyi, as a newly minted PhD, will be back as a postdoc this Summer.

GrUVi members co-author five technical papers at SIGGRAPH Asia 2018, which will be held at Tokyo in December 4-7. In particular, Wallace, Shuhua, Akshay, Manyi, Ali, and Han all got their very first SIG papers! The papers cover topics in fabrication, machine learning, shape and scene modeling, NLP, and even a fun (fabricable) puzzle! The papers are: "Language-Driven Synthesis of 3D Scenes Using Scene Databases", "Construction and Fabrication of Reversible Shape Transforms", "Fabricable Eulerian Wires for 3D Shape Abstraction", "SCORES: Shape Composition with Recursive Substructure Priors", and "3D Fabrication with Universal Building Blocks and Pyramidal Shells". Congratulations to all authors!

× Gruviers Volunteered for SIG'2018

August 23, 2018

Two gruviers were student volunteers (SV) at the SIGGRAPH 2018 conference. While the attendees were certainly thankful for all the work that all the volunteers put in the event, our gruvi volunteers described how valuable the experience was for them! Zhiqin got the chance to use the hardware available at the exhibition hall to print the awesome gruvi logo on the hat shown in the picture. He described the great impact that experiencing the latest developments on VR technology had on him:

"I'm honored to be a student volunteer of such a great conference. VR was definitely a highlight of SIGGRAPH 2018. There were many showcases of applying haptic technology to VR and utilizing VR for designing and creating content. The immersive pavilion was awesome and provided me all kinds of VR experiences. I am looking forward to next SIGGRAPH!"

Akshay, on the other hand, emphasized the connections he was able to forge during his time as a volunteer:

"This was my first SIGGRAPH and my first time as a SIG-SV. The kind of atmosphere, the exuberance of energy and experience that I felt was surreal and I was left wanting for more when it ended. Memories of a lifetime with awesome fellow SV's, coordinating various programs and above all, the latest technology!! Definitely want to relive this again at SIG'19."

August 21, 2018

SIGGRAPH 2018 was held in Vancouver from August 12 to 16, at the Vancouver Convention Centre. The majority of GrUVi members attended the conference, some as paper presenters and some as student volunteers. This year, the lab contributed four papers that were presented in the Technical Papers program. Ali presented his paper on semi-supervised analysis of 3D shape styles and Kangxue presented his paper on P2P-NET, both on Thursday, in the paper session on Shape Analysis. Also notably, long-term collaborator with GrUVi and adjunct professor with the SFU School of Computing Science, Prof. Daniel Cohen-Or, is featured as the annual SIGGRAPH Achievement Award winner. Danny has been collaborating with Richard Zhang and students in the lab since 2008!

× Eugene's 60th Aniversary Celebrated

August 21, 2018

A special event honouring Professor Eugene Fiume, on the occasion of his 60-th birthday, was held at the SFU Harbour Center on August 17, right after SIGGRAPH 2018. Many of Eugene's first-generation PhDs from the University of Toronto attended the celebratory workshop and gave their account of fun and inspiring stories about what it was like to be his graduate students. Eugene's computer graphics instructor during his undergraduate years at the University of Waterloo provided hint of how Eugene was already "ahead of the class" then. The event featured Prof. Pat Hanrahan from Stanford University, as the keynote speaker. Pat spoke of "theory vs. practice" to highlight how over the years, Eugene has been among the rare group of people in computer graphics, who have emphasized the importance of theory in the field.
