1. A method for obtaining information about an occupying item in a space in a vehicle, comprising: arranging an image-obtaining device in the vehicle in a position in which it obtains images of the space when operating; using the image-obtaining device, obtaining images of an area in the vehicle in which the occupying item may be situated, the area being part of the space in the vehicle in which the occupying item may be situated; and using a processor coupled to the image-obtaining device, classifying the occupying item by inputting signals derived from the images obtained by the image-obtaining device into a trained neural network form embodied in the processor, the trained neural network form being trained to output an indication of a class of occupying item from one of a predetermined number of possible classes of occupying items, the class of the occupying item constituting information about the occupying item.
