--- res: bibo_abstract: - The scale invariance of natural images suggests an analogy to the statistical mechanics of physical systems at a critical point. Here we examine the distribution of pixels in small image patches and show how to construct the corresponding thermodynamics. We find evidence for criticality in a diverging specific heat, which corresponds to large fluctuations in how "surprising" we find individual images, and in the quantitative form of the entropy vs energy. We identify special image configurations as local energy minima and show that average patches within each basin are interpretable as lines and edges in all orientations.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Greg foaf_name: Stephens, Greg foaf_surname: Stephens - foaf_Person: foaf_givenName: Thierry foaf_name: Mora, Thierry foaf_surname: Mora - foaf_Person: foaf_givenName: Gasper foaf_name: Tkacik, Gasper foaf_surname: Tkacik foaf_workInfoHomepage: http://www.librecat.org/personId=3D494DCA-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-6699-1455 - foaf_Person: foaf_givenName: William foaf_name: Bialek, William foaf_surname: Bialek bibo_doi: 10.1103/PhysRevLett.110.018701 bibo_issue: '1' bibo_volume: 110 dct_date: 2013^xs_gYear dct_language: eng dct_publisher: American Physical Society@ dct_title: Statistical thermodynamics of natural images@ ...
