Abstract :
This paper presents adaptive image enhancement algorithms which enhance hidden signals in pictures and describes their implementation for real-time video signals. An image enhancement algorithm proposed by Peli and Lim (1981) is extended for application to video signals. A fast implementation algorithm is provided with parallel implementation which enables the practical implementations for video signals using processors with SIMD parallel instructions
