Abstract
The emphasis in this correspondence is on the study of nonstationary t wo-dimensional (2-D) random fields with wide-sense stationary incremen ts, wide-sense stationary jumps, and 2-D fractional Brownian motion (f Bm) fields. The effort made in this work is to develop a realizable me thod of stationarization provided for nonstationary 2-D random fields. We also present the correlation functions of the discrete wavelet tra nsform relating to 2-D fBm fields that will decay hyperbolically fast.
