TL;DR: A texture synthesis algorithm based on the gray-level co-occurrence matrix (GLCM) of a texture field uses a texture similarity metric to generate stipple textures that are perceptually similar to input samples, allowing us to better capture and reproduce stipple distributions.

Illustration-Inspired Depth Enhanced Volumetric Medical Visualization
TL;DR: Inspired by traditional visual and line-drawing techniques found in medical illustration, a collection of fast algorithms for more effective emphasis/de-emphasis of data as well as conveyance of spatial relationships in volumetric datasets are developed.

Measuring Stipple Aesthetics in Hand-Drawn and Computer-Generated Images
Ross Maciejewski,Tobias Isenberg,William M. Andrews,David S. Ebert,Mario Costa Sousa,Wei Chen +5 more
TL;DR: In this article, the authors compare texture stippling in hand-drawn and computer-generated illustrations, using image-processing analysis techniques, and find that the two kinds of images follow different aesthetic principles.
