Abstract：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.
