A pattern processing system associates images input patterns with desired response codes. The image input is stored in an image buffer as an addressable array of sample values. An address sequencer provides a sequence of addresses (or "address stream") to the image buffer and to a response memory. The next address provided by the address sequencer is based upon the current address and the state of the sample value stored in the image buffer at the location corresponding to the current address. Once the address sequencer repeats an address, the address stream is in a repetitive address loop as long as the image stored in the image buffer remains constant. The addressing occurring commonly for the learning samples are detected and subsequently used for identification of unknown patterns. By arranging the sequence generator so as to ensure that the address-sequences have a predetermined minimum length, multiple possible address-sequences are avoided. |
