Many existing methods describe structural or statistical textures. For the transition region, the structural-statistical textures, only very few dedicated methods are known. In this report, a texture model is presented that allows the description of certain structural-statistical textures. The way of looking at modulation from communications technology is applied to textures. A structural texture may be subject to a variation of the gray value, i.e., amplitude modulation, or primitive, i.e., frequency modulation. This is based on the description of the modulated texture using an extended two-dimensional Fourier series. This enables not only the representation of modulated textures, but also the demodulation with the help of a presented phase-locked loop. Thus, an assessment of a modulated texture is achieved.
