We introduce a non-photorealistic rendering technique for transforming an input photograph into a maze-like scratch image. Stripe patterns are generated on the input image with an anisotropic shock filter, and then the edges of the stripes are extracted and thickened. These thickened edges are overdrawn on the input image to produce a maze-like scratch image. Three-dimensional (3D) effects are then added to the maze-like image using bump mapping. The displacement of edges produces a pop-up effect on the maze-like scratch lines.
