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 7/2020) 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 several 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.

Congratulations to Angel Xuan Chang and Manolis Savva, whose work ScanNet: Richly-annotated 3D Reconstructions of Indoor Scenes won the 2020 SGP dataset award. ScanNet is an RGB-D video dataset containing 2.5 million views in more than 1500 scans, annotated with 3D camera poses, surface reconstructions, and instance-level semantic segmentations. More information can be found in the paper here.

Visual computing researchers from SFU received multiple awards at the annual Conference on Computer Vision and Pattern Recognition (CVPR) this past week. CVPR is the premier conference in computer vision with the highest impact factor among all conferences in computer science and was held virtually for the first time this year from June 14-19. Computing science professor Greg Mori served as one of four program chairs at the conference. Zhiqin Chen and Richard Zhang, together with GrUVi alumnus Andrea Tagliasacchi, won the Best Student Paper Award with “BSP-Net: Generating Compact Meshes via Binary Space Partitioning” introduces a deep neural network which applies a classical graphics technique to learn compact shape representations. Yasutaka Furukawa won the PAMI Longuet-Higgins Prize for his CVPR 2007 milestone paper on “multi-view stereo reconstruction”, which has been cited more than 3,000 times! Also, Akshay Gadi Patil won the Best Paper Award at the CVPR Workshop on Text and Documents in the Deep Learning Era for his work “READ: Recursive Autoencoders for Document Layout Generation”.
