Simulated Annealing for JPEG Quantization: Tables

Max Hopkins, Michael Mitzenmacher, Sebastian Wagner-Carena


The tables below relate to the work described in the paper Simulated Annealing for JPEG Quantization. They are JPEG quantization tables that were trained to improve on the standard JPEG table on either compression or feature similarity (FSIM) error. Each table has been trained at a particular quality input, but can be used for any quality input. For a deeper discussion please reference our full paper.
