【摘要】 深入研究了应用数学形态学理论对连杆曲线形状特征进行描述的方法,揭示了连杆曲线形状谱的意义。通过对各种连杆曲线的全面分析,得到了连杆曲线类型与形状谱的内在关系,提出了连杆曲线图形的宽窄程度决定了其形状谱波峰位置的新观点。基于上述结论划分了连杆曲线的特征区域,建立了连杆曲线区域电子图谱库,可有效提高相似曲线的查询速度与效果。更多还原

【Abstract】 We have studied deeply the description about the shape features of linkage curves based on the mathematical morphology theory,and probed the significance of the shape spectrum.Through a comprehensive analysis of various kinds of linkage curves,we obtained the inherent relationship between the types of linkage curves and their corresponding shape spectrums,proposed a new idea that the a linkage curve shape’s width determines the location where its shape spectrum’s crest appears.According to the conclusion,we finished the division of the characteristic regions of linkage curves,constructed the linkage curve regional electronic atlas,which can improve the query speed and effect of similar linkage curves effectively.更多还原
