ABSTRACT:
A method and apparatus for a cellular processing array comprising a plurality of processing cells wherein each cell is capable of detecting intensity changes in a field under observation. The processing cells having one or more outputs connected as inputs to one or more neighboring processing cells and each of the connected inputs is indicative of whether or not its connected neighboring processing cell has detected an intensity change. Means are provided to increment the received inputs if the receiving cell has detected an intensity change from dark to light in consecutive detection cycles and to decrement the received inputs if the receiving cell has detected an intensity change from light to dark in consecutive detection cycles. The inputs as processed are provided as an output to connected neighboring processing cells. No incremental or decremental action on the inputs occurs if the receiving cell has detected light and/or if no intensity change has occurred in consecutive detection cycles, in which case, the inputs as received are provided as outputs to neighboring cells connected to receive output from the receiving output. The incremental or decremental action on received inputs may be a unit value or an amplification factor based upon past detection cycle activity.
