A Template Matching Approach for Reference Picture Padding in Video Coding

ICASSP 2023accepted

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,…

On the Accuracy Limit of Time-delay Estimation with a Band-limited Signal

ICASSP 2019accepted

The derivation of tight estimation lower bounds is a key player to design and assess the performance of new estimators. Considering a generic band-limited signal formulation and constant transmitter to receiver propagation delay, we propose a novel compact closed-form expression of the Cramér-Rao bo…
