Texture Synthesis Based on Wang Tiles

摘要

Texture Synthesis aims to solve the existing problem of seams in texture mapping. It is used to generate an arbitrarily large texture image given an existing small texture sample. For human observers, both the original texture image and the generated one are perceived as the same and the generated one does not contain obvious seams. Non-periodicity is an import principle in texture synthesis. Wang Tiles algorithm is known to synthesize texture according to a color matching rule via designing a Wang Tiles set. We believe if we utilize more tiles and the number of edges of each tile increases, that means, we use more colors, we can reduce periodicity in the synthesized results. The chosen texture tiles in the previous algorithms are mainly rectangular. Combined with Wang Tiles and Quilting algorithms, in this paper we design a hexagonal texture tile. Through the experiment our method is effective and not time-consuming.
