与基于平均线的评价系统相比，模体分析和形态滤波器是两种面向表面功能特性表征的技术。基序组合过程与形态学闭合滤波器的功能一致，即抑制轮廓上的不显著峰。通过将结构元素的功能性与模体组合准则相联系，有效地计算了形态包络。再加上水平线段结构元素的长度相当于图案的粗糙度和波纹度限制的形态关闭过滤器提供了一种替代的图案分析。所提出的形态学方法具有良好的数学基础和稳定性。应用经验基序方法（ISO 12085）和形态学方法的一个例子。两种方法得到的模体参数基本一致。因此，两种不同的面向功能的表面纹理评价方法在技术上相互关联，相互开发。
In contrast to the mean-line based evaluation system, motif analysis and morphological filters are two techniques oriented to the characterization of functional properties of surfaces. The motif combination procedure is consistent with the functionality of the morphological closing filter that insignificant peaks on the profile are suppressed. By linking the functionality of the structuring elements with motif combination criterions, morphological envelopes are computed efficiently. Reversely the morphological closing filter coupled with horizontal line-segment structuring elements with lengths equivalent to the motif limits for roughness and waviness provides an alternative for motif analysis. The proposed morphological method has a sound mathematical basis and is stable. An example of applying the empirical motif method (ISO 12085) and the morphological method is demonstrated. The motif parameters resulted from two methods reveal that they coincide with each other. Thus two distinct function oriented methods for surface texture evaluation are technically correlated by mutual exploitation.
