| Abstract |
Texture synthesis is an important technology for graphics and animation. This paper proposes a novel method based upon the multi-resolution neighborhood matching technique pioneered by Wei and Levoy. Wei and Levoy's simple but powerful method is effective at synthesizing a wide range of textures. However, it has a tendency to produce synthesis artifacts in textures containing distinctive structural elements with large degrees of irregularity, such as stones in a stone wall. We propose several improvements designed to overcome these artifacts: (1) Morphological operations to emphasize key aspects of structure such as edges followed by image analogy to undo the effects of morphology (2) Combining non-causal neighborhoods with causal neighborhoods (3) Appropriate weighting of the parent and current level in the multi-resolution pyramid. Experimental results demonstrate that these modifications improve the quality of synthesis for textures containing irregularly structured components.
