How and why researchers are building a high-quality annotated image library to improve object detection
CCTV cameras in cities are used for community safety and crime prevention applications but most of the time these cameras are not actually in active use.
We are interested in harnessing the redundancy within this ready-made sensor network so that decision makers can better understand how people are using public spaces and to better manage resource constraints.
In this blog, data scientists Luis Serra and Maralbek Zeinullin explain how and why they used annotated images to train computer vision models to be deployed on CCTV cameras.
The data and machine learning training model is now available to other academics and developers wanting to develop or validate their own models.
