    We describe a method to recognize vehicles, in particular to recognize which make it is and which type it is. Our system employs infra-red images so that we can use the same algorithm in day time and at night. The algorithm is based on vector quantization, originally proposed by Krumm (1997), and is implemented on the IMAP parallel image processing board. Our system makes the compressed database o...
