What is the best library (in C, Java, ...) to find a white line on the floor?
By "find a white line" I mean to analyse some images in real-time from a webcam (from a smartphone, extern webcam), do some image processing and get a direction for a robot (through a microcontroler).
Is it possible to program on a smartphone (Android, ios) or a micro controller? (if not, on a computer through a WiFi connection)
