Paper Abstract

Traditionally, the performance of a image compression codec is measured by its rate-distortion curve, where a distortion metric measures the fitness of the reconstructed image for a particular purpose. However, metrics employed here address the needs of professional photography only partially: Images are typically not published as taken, but are post-process to express the intent of the photographer. Compression codecs might degrade the image visibly by an interaction of the codec-specific loss with the editing tools. In this work, we present the idea of application specific metrics and measure the robustness of state of the art compression codecs under prototypical image manipulations.
