  • Change detection for C-IED

    Motivation Improvised Explosive Devices (IEDs) are one of the primary causes of casualties amongst NATO forces in conflict areas. As IEDs are constructed from a large variety of materials, their type and appearance is a-priori unknown. This makes it difficult to find such objects using standard object-recognition techniques, since it is

Accuracy camera counting outperforms measurements via Bluetooth and WiFi

In collaboration with the University of Ghent, ViNotion has counted the visitors of the Ghent Festival in Belgium, during the summer of 2013. To count the visitors of the festival, both a camera counting system was used, and the activities of cell phones were measured using Bluetooth and WiFi signals. The results of these counts were used to improve the flow of people for immediate safety, but also for future safety measures at following events.

The Ghent Festival is one of the biggest festivals in Europe. This year 1.3 million people visited the event. For ten days long there are festivities in the whole city, spread over different locations.


The camera counting system was capable of measuring the amount of people with an accuracy of well above 90%. These results were compared with the measurement of the cell phone Bluetooth / WiFi activities. It appeared that he camera counts are up to 5 times more accurate. It seems that the accuracy of wireless signals varies by external factors, and therefore depends on the location and the time of the measurements. The measurements by the camera counting have a constant high accuracy. Measuring wireless signals appears very suitable for providing relevant additional information, such as the average visiting time of people and the number of times that the visitors repeatedly go to the festival. For more detailed analyzes, the combination of both systems is a good solution.
