基于线性四分树描述的图像块邻域寻找的快速方法

Neighbor Finding Techniques for Image Block Represented by Linear Quadtrees

线性四分树将物体区域表示为组成物体区域的四分块的位置码的集合。本文通过分析位置码属性，归纳出了图像四分块相邻的充要条件，并给出了相应的寻找图像块邻域的算法。该方法简单明了，便于计算机实现。

Linear quadtrees represent image as a set of orientation code of each object region.By analysing the codes of neighbor quad-blocks,a method to find the neighbors of each quad-block is presented,which is much simpler than the existent ones.
