The shape identification includes the local character point and its direction, the curve structure, the global parameter and topology trait.

形态识别包括：局部特征点及其方向，弯曲的结构特征，整体描述参数以及拓扑特征。

Method of identification of the two is to look at the pattern of the wood texture, veneer wood chipping straight and dense, veneer rotary cutting and thinning pattern curve.

当然识别二者的方法是看木材的花纹，刨切的单板木材纹理直而密，旋切的单板花纹曲而疏。

If viewed from fuzzy mathematics, the known logging curve is used as a "pattern", and the correlation of strata is called "pattern identification".

从模糊数学的观点看，当作对比标准的曲线可以视为“模式”，地层相关对比过程是“模式识别”过程。
