This paper is intended as a complement of document n3954 and presents some preliminary evaluation of coding efficiency of a scalable wavelet-based encoder. Two HD video sequences have been encoded according to test conditions derived from those used to evaluate the coding efficiency of JSVM and VidWav[4]. Assuming that exploiting temporal redundancy in video coding improves compression efficiency, the aim of this work is to further investigate advantage and disadvantage of applying a motion compensated temporal filtering, in term of compression gain, with respect to pure intra coding.

Abstract
This paper is intended as a complement of document n3954 and presents some preliminary evaluation of coding efficiency of a scalable wavelet-based encoder. Two HD video sequences have been encoded according to test conditions derived from those used to evaluate the coding efficiency of JSVM and VidWav[4]. Assuming that exploiting temporal redundancy in video coding improves compression efficiency, the aim of this work is to further investigate advantage and disadvantage of applying a motion compensated temporal filtering, in term of compression gain, with respect to pure intra coding.File in questo prodotto:
