Unconstrained motion compensated temporal filtering (UMCTF) is a very general and flexible framework for temporal filtering. It allows the selection of many different filters as well as decomposition structures to allow easy adaptation to video content, bandwidth variations, complexity requirements, and in conjunction with embedded coding can provide spatio-temporal-SNR scalability. In this paper we demonstrate the content-adaptive filter selection provided within the UMCTF framework. We show improvements in coding efficiency as well as in decoded visual quality using content-adaptive filters, at different granularities.
