  2. Introduction Introduction Who am I? What do I do here? 2

  3. About me Short research bio: - 2014 - finished PhD at FMFI UK - 2014 – 2016 - researcher & freelancer - 2016 – 2017 - PostDoc Researcher at TU Wien - 2017 – now - CEO, Research lead at Skeletex Research Collaboration with universities: - 2015 – 2018 - research assistant FMFI UK - 2018 – now - assistant professor at FIIT STU - 2018 – now - assistant professor at FMFI UK 3

  4. What do I do here Explain basic principles of computer graphics and computer vision in - context of VR/AR applications Tell a story about me, computer graphics and interesting projects - Motivate you, students, into CG and CV - Create some kind of collaboration between students and our company - 4

  5. What does Skeletex Research do Freelancing research and development company - What we used to do: - motion capture, skeleton tracking, human body fusion, 3D cameras - Currently we are working on: - 3D scanners, scan registration, mesh reconstruction, point cloud segmentation - Cooperation with universities: - lectures, theses supervision, internships, research, publications - Cooperation with tech companies: - research and development - 5

  6. Previous projects Openworm - Skeleton-based compression of particle simulation - Kinexact - Automatic extraction of skeleton - Hand scans - Optical-Inertial hybrid tracking of skeleton - Webcam based - Skeleton tracking and body fusion - Texture-space surface fusion - Skeletex data structure - 6

  7. 3D reconstructions and skeletons 7

  13. Human skeleton tracking and fusion 13

  14. Skeletex data structure 14

  15. Skeletex data structure 15

  16. Our main goal Capture human motion - Reconstruct in VR - 16

  17. Current projects 3D scan segmentation - Real-time (for 60fps camera) - CUDA implementation for GPU and TegraTX1, TX2 build in camera - Use hierarchical structure and flood fill approximation - 3D scan registration - Iterative Closes Point with fast camera space projections - Global optimization (use of scan graph) - Tracking (if real-time) - 3D model fusion and reconstruction - Multi-view filtering + Outlier removal - Dynamic and progressive triangulation - Rigid / Non-rigid? Real-time? - 17

  18. Point cloud segmentation Real-time CUDA point cloud segmentation - a) calculate metrics based on curvature and distance - b) threshold the metrics - c) fill regions in parallel (accelerated by hierarchical structure) - 18

  19. PRAFOS Point cloud Rigid Alignment and Fusion of Scans 19

  20. Rotable - Point cloud Rigid Alignment and Fusion of Scans 20

  23. PCVR 23

  24. RAVOS 24

  25. BinSim  Synthetic data generation for ML  Physically-based simulation & virtual scanning 25

  26. HIRO 26

  27. Why CG? Common view… Computer Games Development - Common motivation - Ain’t no fun, very hard :/ - Hard business - Financial problems / hard with capital investment - CG skills can be used in other fields as well: - Film industry - Medical applications - 3D printing - 3D scanning - Optical systems - Other software - 27

  28. Situation Slovakia, Bratislava T ech companies, Startups Jobs, University research 28

  29. Companies CG and years 2010 vs 2014 vs 2019/2020 - CG Companies in Bratislava - Photoneo - Capturing Reality - Vectary - etc. - CG Companies in Wien - VRVIS - Procedural Design - CG Companies in Czech - Corona - 29

  30. Companies “The Danube Valley” 30

  31. Universities STU FIIT - Principles of Computer Graphics and Image Processing - Advanced Computer Graphics Methods - more computer vision courses - FMFI UK - Fundamentals of Computer Graphics and Image Processing - Advanced Computer Graphics - Virtual and Augmented Reality - Real-time Rendering - more computer vision courses - You can focus on CG along projects during the study - The most important – your B&D Theses! - 31

  32. Why to collaborate with Skeletex If you want to do graphics in you professional life after graduation - Try it in pro way, get used to such a cooperation during study - State of the art research - Cooperation of high-end startups and universities - Be guided by top experts in the field - Winners of student conferences - CESCG - ŠVOČ - PhD. Students internships - MIT - MPII - 32
