循环运动正式定义为沿运动路径重复曲率值。提出了使用时空 (ST) 表面和 ST 曲线进行循环运动检测的过程。对象的投影运动会生成 ST 曲面。在 ST 表面上检测 ST 曲线，提供 ST 表面的准确、紧凑、定性描述。然后使用 ST 曲线的曲率尺度空间来检测重复曲率值的间隔。展示了两个数据集中循环运动的成功检测。>
Cyclic motion is formally defined as repeating curvature values along a path of motion. A procedure is presented for cyclic motion detection using spatiotemporal (ST) surfaces and ST curves. The projected movement of an object generates ST surfaces. ST curves are detected on the ST surfaces, providing an accurate, compact, qualitative description of the ST surfaces. Curvature scale-space of the ST curves is then used to detect intervals of repeating curvature values. The successful detection of cyclic motion in two data sets is presented.>
