齿中线是用于判定沉积相的比较重要的方法.首先提出了当数列中连续多个值相等且为极大值/极小值时,求中间极大值/极小值点的算法;然后提出了用于计算和判断齿中线形态的算法,该算法包括求曲线极大值和极小值、计算齿中线倾角、判决齿中线形态等步骤.经过在仿真数据上测试,表明改方法能够降低曲线中的噪声,并能够准确地检测到各个极大值和极小值点,在计算各个极值点的齿中线倾角后,能够判断齿中线的收敛类型.

Tooth midline is a method for judging sedimentary facies.An algorithm for obtaining maximum/minimum value is described when several successive values which are maximum /minimum values are equal.Then an algorithm is proposed for computing tooth midline and judging pattern of tooth midline, which contains several steps,including computing maximum /minimum value,computing dip angle of the tooth midline,and judging pattern of the tooth midline.Several tests on simulated data sets show that the proposed algorithm reduced noise in the curve, and detected each maximum /minimum value correctly. The pattern of convergence was determined after tooth midline of each extreme value is computed.
