Selective Extraction of Entangled Textures via Adaptive PDE Transform

Figure 1

Extraction of various embedded textures using the PDE transform. (a) shows the original image composed of various horizontal and vertical textures. (b)–(d) show the three texture patterns extracted by applying the PDE transform, one at each time. (e) shows the edge mode obtained by applying the PDE transform to (a). (f) shows the variance of the local variation of the image mode function (e). (g) and (h) show the projection, or average, of the variance in (f) along 𝑥- and 𝑦-direction, respectively.
