摘要: | The correspondence explores the ergodicity property of the two-dimensional (2-D) discrete wavelet transform for a fractional Brownian motion (fBm) field that consists of one approximation image and three detail images. In this correspondence, the decorrelation and ergodicity of the three detail images of fBm fields are shown to he achieved. |
