I am looking for good methods, preferably parameterless, to detect textured areas in an image. I mean random textures, not regular patterns. The final goal is to discriminate between significant edges and false edges in texture, which can have a significant intensity.

In my opinion, a discriminative characteristic of textured areas is that the gradient direction can strongly from pixel to pixel, but I have found no good way to rate this. In particular, the random behavior makes local estimators fairly unstable.

I am aware of the technique of surround suppression proposed by Grigorescu, Petkov et al., but I would prefer a detection technique that works independently of the presence of true edges, such as a texturedness indicator. I also know the interesting paper "Detection of Textured Areas in Images Using a Disorganization Indicator Based on Component Counts, Ruth Bergman, H. Nachlieli, G. Ruckenstein", which goes in a nice direction.

Are you aware of alternative techniques ?

Please note that my question is not about texture edges (boundary between different textures).
