Multiresolution Sampling Procedure For the Analysis And Synthesis Of Texture Images

Approach: The approach presented here uses the results psychophysical models to provide constraints on a statistical sampling procedure. In a two-phase process, the input texture is first analyzed by measuring the joint occurrence, across multiple resolutions, of several of the features used in psychophysical models. In the second phase, a new texture is synthesized by sampling successive spatial frequency bands from the input texture, conditioned on the similar joint occurrence of features at all lower spatial frequencies. By rearranging textural components at locations and resolutions where the discriminability is below threshold, new texture samples are generated which have similar visual characteristics. Several results of this method are shown in Figure 1.
