I am looking for an Android application that can detect police or speed radar presence by using the camera when driving. (i.e. based on object recognition, not database-based like this question looking for an app showing typical police traps locations)
Any price is good. If location specific (since cop colors and equipment change from place to place), I am mostly interested in the US, specifically California and Massachusetts.
Same question for iOS: iOS app to detect police or speed radar presence
