Real-Time Adaptive Image Compression: A Machine Learning Approach
In their paper "Real-Time Adaptive Image Compression," authors Oren Rippel and Lubomir Bourdev present a machine learning-based approach to lossy image compression that outperforms all existing codecs while running in real-time. This new approach represents a significant improvement over existing codecs both in terms of compression ratio and speed of operation, with potential applications in fields such as video streaming.
Background
Lossy image compression is an important tool for reducing the size of digital images without sacrificing too much quality. It is used across many industries, from web design to medical imaging, to reduce bandwidth requirements or storage space. However, most existing methods are limited by either slow speeds or poor compression ratios.
The Algorithm
Rippel and Bourdev's algorithm is designed to be lightweight and deployable, with the ability to encode or decode the Kodak dataset in around 10ms per image on GPU. The architecture is an autoencoder featuring pyramidal analysis, an adaptive coding module, and regularization of the expected codelength. Additionally, the approach is supplemented with adversarial training specialized towards use in a compression setting, enabling visually pleasing reconstructions for very low bitrates.
The algorithm typically produces files 2.5 times smaller than JPEG and JPEG 2000, 2 times smaller than WebP, and 1.7 times smaller than BPG on datasets of generic images across all quality levels. This represents a significant improvement over existing codecs both in terms of compression ratio and speed of operation compared to other methods available today.

We present a machine learning-based approach to lossy image compression which outperforms all existing codecs, while running in real-time. Our algorithm typically produces files 2.5 times smaller than JPEG and JPEG 2000, 2 times smaller than WebP, and 1.7 times smaller than BPG on datasets of generic images across all quality levels. At the same time, our codec is designed to be lightweight and deployable: for example, it can encode or decode the Kodak dataset in around 10ms per image on GPU. Our architecture is an autoencoder featuring pyramidal analysis, an adaptive coding module, and regularization of the expected codelength. We also supplement our approach with adversarial training specialized towards use in a compression setting: this enables us to produce visually pleasing reconstructions for very low bitrates.
