In this paper, a temporally adaptive layered image coding technique em
ploying the 3D subband coding is proposed. By using the R-D performanc
e measure, the input image is divided adaptively into temporal image l
ayers, according to the temporal activity. Then, while the base layer
is encoded by the H.261, the enhancement layer is encoded by the 3D SE
C technique. From the simulation results, the proposed technique shows
about 1 dB PSNR gain over the conventional layered coding techniques,
including the twin-H.261, even under heavy network loading. (C) 1998
