Teo de Campos Publications Students Projects Datasets Teaching Demos CV I am a Computer Vision / Deep Learning Scientist at Vicon Motion Systems (a member of the Oxford Metrics Group). I am also a member of the University of Brasilia (UnB), where I have worked as a "professor" since 2016. However, since June 2021, I have been holding a leave of abscense from UnB and for this reason I am not planning to accept to supervise new students for the time being. I am also linked with the CVSSP/University of Surrey, as a "visiting researcher", where I had worked as a senior research fellow from 2009 to 2016. From March 2013 to April 2014 I'd also worked in the Machine Learning group at the University of Sheffield. Previously, I have worked in the research laboratories of Xerox, Microsoft and Sharp. I completed my DPhil in 2006 at the University of Oxford and my award winning MPhil thesis at the University of Sao Paulo, in 2001. My research interests include a wide range of computer vision applications, natural language processing, transfer learning, anomaly detection, head tracking for spatial audio and semantic image segmentation.

Projects

Here is a list of projects, showing the period in which I have been involved (not necessarily the duration of the project as a whole):

• I am the Principal Investigator of project KnEDLe - Knowledge Extraction from Documents of LEgal content (2020-2022)
• Follow this link to see the projects of UnBVision, my group at GitLab, which include the projects below (among others):
• Semantic Scene Completion from 360 cameras (2019-present)
• EdgeNet - 3D Semantic Segmentation using depth and 2D edges.
• TF-SSCnet, Aloisio's implementation of SSCNet (which was originally written in Caffe) using TensorFlow. This implementation has a much smaller memory footprint than the original code and it also separates pre-processing steps from the neural net pipeline, making training a lot faster.
• Domain Adaptation for person re-identification (2018-present).
• SkinNet - our deep CNN for skin detection
• Victor Project: an AI system for Brazil's supreme court (2018-2019)
