DecoBrush: Drawing Structured Decorative Patterns by Example

摘要

Structured decorative patterns are common ornamentations in a varietyrnof media like books, web pages, greeting cards and interiorrndesign. Creating such art from scratch using conventional softwarernis time consuming for experts and daunting for novices. We introducernDecoBrush, a data-driven drawing system that generalizes thernconventional digital “painting” concept beyond the scope of naturalrnmedia to allow synthesis of structured decorative patterns followingrnuser-sketched paths. The user simply selects an example libraryrnand draws the overall shape of a pattern. DecoBrush then synthesizesrna shape in the style of the exemplars but roughly matchingrnthe overall shape. If the designer wishes to alter the result, Deco-rnBrush also supports user-guided refinement via simple drawing andrnerasing tools. For a variety of example styles, we demonstrate highqualityrnuser-constrained synthesized patterns that visually resemblernthe exemplars while exhibiting plausible structural variations.
