Graffiti on public transport and in public spaces can create a negative images of the local environment and make users feel unsafe and even anxious. If graffiti is not removed then this can even encourage less respect for our amenities. At Elter we have developed a system to help public transport companies to spot graffiti on its rolling stock in partnership with Hikvision. The graffiti is identified using our AI system, and this data is provided to the maintenance people so that they can quickly schedule their intervention.
