Abstract :
A parallel neural network for finding the median of an array of nonnegative integers is proposed. The processing time of the network is equal to the time delay of five neurons. This is constant irrespective of the number of elements in the array. This is in contrast with the conventional serial and parallel implementations where the delay time increases as the array gets larger. The proposed network makes the real-time enhancement of images and video pictures possible.<>
