Abstract
In this paper we present a pixel-based approach to the production of pencil sketch style images. Input pixels are mapped, using their intensity via a texture-map, to the output sketches. Conceptually, pixels are grouped into regions and the texture obtained from the Texture-map is applied to the output image for a given region. The hatchings and cross-hatchings textures give the resultant images the likeness of pencil sketches. By altering the texture-map applied during the transformation, good results can be obtained, often closely mimicking human sketches. We present details of our approach and give example of sketches. In future work, we wish to enrich the texture-maps so that the texture could better reflect or hint the surface properties of objects in the scene (e.g., hardness, softness, etc.).
