     "The original paper uses synthesis to demonstrate the role of these different types of statistics.  They show that the statistics can be used to constrain a synthesis optimization to generate new examples of textures.  They also show that the absence of subsets of statistics results in synthesis failures.  Here we replicate those results.\n",
