This paper presents adaptive image enhancement algorithms which enhance hidden signals in the pictures and describes their implementation for real-time video signals. An image enhancement algorithm proposed by T. Peli and J. S. Lim is extended for application to video signals. A fast implementation algorithm is provided with parallel implementation. The proposed algorithms are shown to be realized in real-time on 200 MHz microprocessors with multimedia extensions for 720 480 (pixels) 30 frames/sec video signals.
