Optimal approximation model of autocorrelation function of digital image

Optimal approximation model of autocorrelation function of digital image

Non-stationary stochastic signal was divided into piecewise stationary stochastic signal,and reflecting the sig-nal’s characteristics by autocorrelation function of the piecewise stationary stochastic signal.Generally,the autocorrela-tion function was the base of selecting signal base for signal rep...
