abstract = "Patch-based texture synthesis builds a texture by joining together
blocks of pixels -- patches -- of the original sample. Usually the
best patches are selected among all possible using a \$L2\$ norm
on the RGB or grayscale pixel values of boundary zones. The
\$L2\$ metric provides the raw pixel-to-pixel difference,
disregarding relevant image structures -- such as edges -- that
are relevant in the human visual system and therefore on synthesis
of new textures. We present a wavelet-based approach for selecting
patches for patch-based texture synthesis. For each possible patch
we compute the wavelet coefficients for the boundary region and
pick the patch with the smallest error computed from the wavelet
coefficients. We show that the use of wavelets as metric for
selection of the best patches improves texture synthesis for
samples which previous work fails, mainly textures with prominent
aligned features..",
