分析了全球剖分格网与影像金字塔的优点与不足，结合两者的优势提出了剖分影像金字塔模型及建塔策略，利用全球剖分格网面片编码的唯一性和Hilbert曲线空间连续性对影像块进行索引与组织。

A new method of automatic segmentation is developed based on the extreme point properties of wavelet transform. The method consists of two main steps: 1. Using the multi-resolution properties of wavelet transform, we can get the information of shape variation with space coordination.

该方法包括两个主要步骤，一是利用小波变换的多分辨率特性得到测井曲线的形态特性随空间坐标的变化信息；二是利用小波变换过零点的特征在不同尺度上的反映，提取不同尺度下的奇异点作为分层的待参考点，结合实际情况最终确定分层点。
