Approaches • First approach – toy with some noise image until it matches the statistics of the input image. Texture Spectrum 12

Approaches • Newer approach – Copy pixels directly from the input. Search instead of model. Texture Spectrum 13

Approaches • Newest approach – Copy patches directly from the input and worry about stitching them together Texture Spectrum 14

Approaches • Newest approach – Copy patches directly from the input and worry about stitching them together while enforcing periodicity. Texture Spectrum 15
