    Abstract: Methods and systems for improving driver visibility during bad weather and/or poor lighting for objects such as road signs, road lines, road markings, etc. The disclosed approach can enhance the captured images by exploiting priori knowledge about the scene and the objects that are stored in a database. In general, the orientation and location of a vehicle can be determined, and data can be retrieved which is indicative of stationary objects that are anticipated to be detectable at a current orientation and location of the vehicle. A captured scene is compared to data retrieved from the database using the information regarding the orientation and the location of the vehicle such that a matching scene indicates where objects are expected to appear in the captured scene and improve driver visibility with respect to the vehicle during poor driving conditions.

    Abstract: Images with respect to an object at an ordering, payment, and delivery locations can be captured utilizing an image capturing system. Capture can be after detecting the presence of the object at each location utilizing an object presence sensor. The captured image can be processed to associate it with a signature and can also be processed in order to extract a small region of interest (e.g., license plate) and can be reduced to a unique signature. Signature can be stored into a database together with the corresponding order and images. Signatures can be matched. The order associated with the object matched by the system together with at least one of the images captured at the delivery point and the order point can be displayed at a user interface located at the payment/delivery point to ensure that the right order is delivered to the right customer asscoiated with the object.
