The text deals with the problem of imitation of images with the quasi-isotropy properties. The properties are obtained by using of a special class of models, namely autoregressions with multiple roots of characteristic equations. Particular attention is paid to the construction of a general model of such random fields on multidimensional grids. In addition, we describe in detail the filtration efficiency of two-dimensional random fields. We compare and analyze the results for models of different multiplicities.
