Technical Papers: Watch presentations by the authors and read their technical papers on machine learning, including an introduction to Supernova, a deep learning-based image/video quality enhancement platform and the application of machine learning in video processing.
In this session we look at two state of the art machine learning based video enhancement systems. The paper from SK Telekom reports on a tool that performs up-conversion, frame interpolation and aspect ratio adjustment, common tasks for any content provider. Whilst the paper from the BBC demonstrates a machine learnt up-conversion filter, offering a demonstrably useful improvement in modern video codec design and asks, can you trust your algorithm? Both a serious and a fascinating question when you consider the risk of bias as your algorithm goes about “improving” skin tones and “enhancing” facial features. There are also two excellent supporting papers from RheinMain University and Shanghai Jiao Tong University, which between them discuss machine learnt inverse tone mapping and gamut extension (of particular relevance in HDR) as well as up-conversion.
