Supplementary Materials: Neural FFTs for Universal Texture Image Synthesis

Unless otherwise stated, the evaluation setup mimics the setup adopted in the main paper. Note, fast Fourier transform (FFT) is an efficient implementation of DFT. The first two authors equally contributed. There is no gold standard image quality metric, and most previous work on texture synthesis only provide visual comparison. Table I below lists the average quality metrics for 5,000 test examples. It cannot directly take the small 128x128 texture patch as the input.
