Abstract
The article 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. The decorrelation and ergodicity of the three detail images of fBm fields are shown to be achieved
