Fourier Descriptors with Different Shape Signatures: a Comparative Study for Shape Based Retrieval of Kinematic Constraints
Fourier Descriptors Kinematic Constraints Shape Based Retrieval
2011/8/5
Fourier Descriptors (FD) has been widely used in image analysis and computer vision for shape recognition as they can be made independent of translation, rotation, as well as scaling. They have also b...

提出用“复合铰链零错位”分析机构结构的方法。先将复合铰链错位成相互距离为零的运动副，建立拓扑图和对应的关联矩阵，确定树及余树，通过矩阵计算求出基本回路矩阵，并进而求出完全回路矩阵。将错位的复合铰链重新合并，根据回路的权排序，再按回路的相互独立性和回路连通性找出优选的独立回路。研究表明，复合铰链零错位后绘制的拓扑图简洁、直观，关联矩阵的建立以及分析回路的算法通用，便于应用在计算机自动结构分析与运动分...
