A novel adaptive vector quantization (VQ) based subband coding scheme for very low bit rate coding of video sequences is presented. Overlapped block motion estimation/compensation is employed to exploit interframe redundancy. A two-dimensional (2-D) wavelet transform (WT) is applied to the resulting displaced frame difference (DFD) signal. The WT coefficients are encoded using an adaptive subband vector quantization (ASBVQ) scheme in combination with a dynamic bit allocation strategy based on marginal analysis. Fixed rate coding is provided. Comparative experimental results of the ASBVQ codec with the H.261 and the H.263 video coding standards are given
