Abstract: 

In this thesis inspired by artists such as Gustave Dore and Copperplate engravers, we propose an approach for producing hatching and engraving effects from depth images. The goal is to generate the engraved style with curves that convey the shape of objects in the depth map. We oversegment the image and then place a group of parallel lines within each region; then, vertices of the lines are displaced according to the depth values in the input depth image. We increase stroke density via cross-hatching in shadowed regions of the image, estimated using the normals of the depth map. The final curves are rendered as splines to produce a resolution independent engraving style image.
