On the basis of the linkage relationship of gravity center of moving segment and gravity center of human body, the principle of circle of gravity center of human body is proposed. 在验证了运动环节重心与人体总重心之间存在联动关系的正确性的基础上,总结提出了人体总重心圆原理。
Carry out region growing by combining single linkage region growing method and centroid linkage region growing method to get the line segment representation of the second catalog road boundaries. 结合单一型链接区域生长和质心型链接区域生长技术进行区域生长,得到第二类道路边界的线段表示。
