Introduction
• An old problem: texture synthesis and processing
• New perspective: explicit control spatial patterns
Introduction
• Many materials have fine-scale textures with large-scale spatial pattern
how to optimize, transfer, and control the spatial patterns in textures
Introduction
• The goal: utilize computed representations of partial and approximate symmetries to guide texture synthesis and manipulation
• Key idea: Operate in a symmetry space which represents spatial patterns
Symmetry• How to measure the spatial patterns in a
image
image f The spatial pattern ST(f)
Symmetry transferSource image: f
Target pattern image: g

Results
Symmetry filtering

Limitations
• Sometimes the texture perturbation model is not flexible enough to generate an output image
Conclusion
• Proposed a framework for symmetry-guided synthesis and processing of textures
