Image Processing Based on Design of Logic Circuit

Hardware-speedup of algorithm based on design of logic circuit can improve capability of real-time processing,integration level and reliability of systems.Computation of image histogram and extracting of pixel-neighborhood are two basic operations in image processing.The methods based on the design of logic circuit to solve these basic problems are introduced.The figures of hardware-structures and some important timing waveforms are presented.The design had been used in our projects and the circuits work well.
