This disclosure pertains to devices, methods, systems, and computer readable media for generating andor interpreting image metadata to determine input parameters for various image processing routines, e. The method includes receiving a sequence of user-bits and calculating a running digital sum of the system. The particles are heated to cure the binder, and the organic particles pyrolyse to form pores in the coating. When the edge lines striding over the connected parts in the overhead image 205 are discontinuous, the image detecting unit 54 sets edge lines at the far side of the own vehicle to match edge lines at the near side of the own vehicle, thereby setting the edge lines continuous at the connected parts.
