Reference Picture Padding removes the restriction for motion vectors to point completely inside the reference picture. Removing this restriction increases the compression efficiency and is, therefore, applied in many video coding standards. However, artifacts can occur at the picture boundaries if t…
Reference picture padding is needed in areas close to the picture boundary. It lifts the restriction of motion vectors not to point over the boundary when using inter prediction. Especially, when independently decodable subpictures are used e.g. in viewport-adaptive streaming, many boundaries occur,…
Informed source separation (ISS) uses source separation for extracting audio objects out of their downmix given some pre-computed parameters. In recent years, non-negative tensor factorization (NTF) has proven to be a good choice for compressing audio objects at an encoding stage. At the decoding st…
Informed Source Separation (ISS) is a topic unifying the research fields of both source separation and source coding. Its main objective is to recover audio objects out of a mixture with a source separation step assisted by a set of compact parameters extracted with complete knowledge of the sources…
