Vision Semantics was founded by Professor Sean Gong, Bob Koger, and Adam Daykin and spun out from Queen Mary, University of London. The objective was to a build a world class software company based on Prof Sean Gong’s research. Since 2014, Vision Semantics has developed a commercial platform for rapid video forensic analysis which is licensed to commercial partners. 

Sean Gong is Co-Founder, CTO and the Chief Scientist at Vision Semantics Ltd

He is a world-authority on Person Re-Identification research and technology deployment for law enforcement video forensic analytics. He is a pioneer in computer vision and machine learning for visual surveillance. He served on the Steering Panel of the UK Government Chief Scientific Adviser's Science Review.

He has published over 300 research papers in computer vision and machine learning. He has authored and edited 7 books on Person Re-Identification, Visual Analysis of Behaviour, Video Analytics for Business Intelligence, Dynamic Vision from Images to Face Recognition, Analysis and Modelling of Faces and Gestures. His recent work includes Transfer Learning, Unsupervised and Semi-Supervised Deep Learning, Imbalanced Data Deep Learning, Deep Reinforcement Learning, Attention and Memory in Deep Learning, Zero-Shot Learning, and Human-In-The-Loop Active Learning.

He was a research fellow on the EU ESPRIT-II project VIEWS (Visual Interpretation and Evaluation of Wide-area Scenes) in 1989-1993, the world’s first multinational collaborative computer vision project on visual surveillance in urban environments. He led the EU FP7 Security Programme SAMURAI (Suspicious and Abnormal Behaviour Monitoring Using a Network of Cameras for Situation Awareness Enhancement) that pioneered Person Re-Identification (Re-ID) for public transport infrastructure protection in 2008-2011. Between 2009-2013, he led the UK government project on developing a system for Multi-Camera Tracking of Objects by Re-ID under the INSTINCT Programme, in collaboration with the BAE Systems.


He founded the Queen Mary Computer Vision Laboratory in 1993. He has been the Professor of Visual Computation at Queen Mary University of London since 2001. He is a Fellow of IEE (now IET), a Fellow of the British Computer Society, and a Member of the UK Computing Research Committee. He has been a Turing Fellow of the Alan Turing Institute of Data Science and Artificial Intelligence, and was a Royal Society Research Fellow.

Our values about data & individual privacy


Vision Semantics Systems are designed to protect individual data privacy, our systems never store any personal data and do not require large data training sets.  The goal has always been to eliminate the perceived trade-offs between privacy and real-world solutions. To do so, we treat privacy as a first-order concern at every stage of workflow process, we search for data matches, but we never see the data or store the data.

Decisions that can affect individuals' rights to freedom and public safety cannot be left solely to AI computers. Our partners & customers are using vision data analytics to inform decisions with significant implications for individuals. Rather than relying on AI algorithms that inhibit accountability, we always build ‘humans in the loop’ to make necessary judgment calls based on their context and experience.


At Vision Semantics, we build software platforms that help our customers integrate and analyse their own visual data in ways that are consistent with legal and ethical considerations. As a company, we do not collect data, sell data, or facilitate unauthorized sharing of data among customers or any other parties.


Our vision that AI can build a better world

Our team is dedicated to working on technology solutions that deliver a better world and doing what's right, in addition to being deeply passionate about building great software and an exciting company to work in.

We have an open culture with critical debate around the implications of AI technology. This ensures that we remain true to our beliefs, even as the markets and countries where we partner evolve. 


At Vision Semantics, we believe technology can enable advancement of the quality of life, helping with the challenges in climate change, medical research and better public safety. We also believe AI applications should remain under meaningful human control and used for socially beneficial purposes. We believe research should be shared and the benefits of technology should be distributed so it benefits society as a whole.
