摘要: Surface curvature along extremal boundaries is potentially useful information for navigation, grasping and object identification tasks. Previous theories have shown that qualitative about can be obtained from a static view. Furthermore it known that, orthographic projection, under planar viewer-motion, quantitative available spatio-temporal derivatives of flow. This theory extended here to arbitrary curvilinear viewer-motion perspective projection.
