Amplitude spectra of natural images look surprisingly alike. Their shape is governed by the famous 1/fpower law. In this work we propose a novel low parameter model for describing these spectra. TheSum-of-Superellipsesconserves their common falloff behavior while simultaneously capturing the dimensions of variation—concavity, isotropy, slope, main orientation—in a small set of meaningful illustrative parameters. We demonstrate its general usefulness in standard computer vision tasks like scene recognition and image compression.
