Predicting and Optimizing Image Compression

Oleksandr Murashko, John Thomson, Hugh Leather
2016 Proceedings of the 2016 ACM on Multimedia Conference - MM '16  
Predicting the effectiveness of standard compression implementations like libjpeg and WebP on a novel image is challenging, and often leads to non-optimal compression.  ...  Using this model, we can actively adapt the aggressiveness of compression on a per image basis to accurately fit user requirements, leading to a more optimal compression.  ...  RESULTS We present results in terms of the accuracy of predictions, and in real-world use case scenarios where we use the models to actually find optimal compression parameters.  ...
