This paper describes an algorithm of video coding based on a three dimensional spatio temporal subband decomposition,and results are shown for a 112kb/s coder that is based on an unbalanced tree structured vector quantizer(UTSVQ) for the lowest frequency band and geometic vector quantizer (GVQ) for the higher frequency bands.
介绍一种视频图像三维子带编码方法，它采用非对称滤波器进行子带划分，对各子带进行量化时，低频子带采用非对称树结构矢量量化方法，高频子带采用几何矢量量化方法。

The main methods include:1) Invariant local feature regions are generated using locally most stable feature points of images;2) An approach is proposed to rapidly find the best image regular geometric flow in these local feature regions;and 3) An orthogonal vector is designed to extract the watermark blindly.
采取的主要方法有:1)利用图像中的局部最稳定特征点生成具有几何不变性的局部特征区域;2)在局部特征分块中快速寻找最佳几何流方向,近似最佳逼近效果;3)设计了一种正交向量盲提取水印。
