摘　　要：最近有文献报道图像序列的三维子波变换压缩编码。本文讨论了多维多分辨率分析和三维子带系统完全重构的充分必要条件，我们对８帧图像序列进行三级三维子波变换，然后进行零树量化和熵编码，文中给出了不同压缩比下的信噪比。编码器可以在要求的任意压缩比下停止编码，如同图修的二维子波零树编码。D wavelet transform compression coding for image seqUences has been reported recently .The paper discusses multidimensaioal multiresolution analysis and the sufficient and necessary conditions of 3D subband sytem allowing perfect reconstruction .We use zerotree quantizatin and entropy coding after three resolution levels 3D wavelet transform of & frames image seqUences.The paper gives the compression ratio with different PSNR.The encoder can terminate the encoding at any point thereby allowing a target compression ratio just as 2D wavelet transform zerotree coding of image.
