Physics and image data compression

摘要

Abstract: We show how several basic image compression methods (predictive coding, transform coding, and pyramid coding) are based on self- similarity, and a 1/f$+2$/ power law. Phase transitions often show self-similarity which is characterized by a spectral power law. Natural images often show a self-similarity which is also characterized by a power law spectrum which is near 1/f$+2$/. Exploring physical analogs leads to greater unity among current methods of compression and perhaps lead to improved techniques.!10
