Probabilistic Image Modelling

Lead Research Organisation: University College London
Department Name: Computer Science


To study applications of, and improvements to, probabilistic modelling of images. In particular the application towards lossless compression, which is poorly understood by the research community, and fundamental improvements in image modelling techniques. These applications and techniques are built around using neural networks to model the images.

Description We have improved the state-of-the-art for lossless image compression through machine learning. We have in principal shown that a system trained on data can compress images to smaller sizes than any existing systems, in a practical manner.
Exploitation Route Image compression is highly relevant for many other fields, since data is abundant these days and we are looking to reduce the footprint it produces.
Sectors Digital/Communication/Information Technologies (including Software)

Description These findings are beginning to be used and investigated by industry, namely large technology companies who have an interest in furthering lossless image compression.
