图象的结点属性码表示法

Image representation technique with node attribution code

给出了一种新的数字图象编码技术。该法采用多级合并方式形成具有最大四分域的四分图象树。在对此四分图象树进行编码表示时，四分图象树的每一结点仅需１比特即可表示出其树状结构信息。由结点属性码还可合成出蕴含有各叶结点几何信息的Ｑ码。

A new technique about image compaction is presented. Multi-level merg- ence process is used to generate quadtree. When the quadtree is encoded with the node attribution code, the each node in the quadtree only need one bit to represent the structure information of the quadtree. In addition,the quadcode that contains geometric information of image can be acquired by the node attri- bution code.
