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

Symmetry transferSource image: f

Results

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
