Selective Extraction of Entangled Textures via Adaptive PDE Transform
PDE transform is applied on (a) to extract edges of all textures into 5(b). Adaptive PDE transform is then applied to extract different textures from 5(b). In 5(c)–5(f), all the textures are superimposed on the original image for better viewing.
(a) Original image
(b) Image mode function
(c) Texture 1
(d) Texture 2
(e) Texture 3
(f) Texture 4
