In this paper we proved that every g-Riesz basis for Hilbert space $H$ with respect to $K$ by adding a condition is a Riesz basis for Hilbert $B(K)$-module $B(H,K)$. This is an extension of [A. Askarizadeh, M. A. Dehghan, {em G-frames as special frames}, Turk. J. Math., 35, (2011) 1-11]. Also, we derived similar results for g-orthonormal and orthogonal bases. Some relationships between dual fra...

A subband approach to scalable multiresolution video coding is presented. In a first step of experiments this scheme is applied to the coding of I–frames, where bit rate savings up to 21.1% compared with MPEG–2 spatial scalability are achieved. In a next step it will be used for inter–frame coding of P– and B–frames.
