Helicoidal flow is a contributing factor to the formation of slip-off slopes and river cliffs in a meandering section of the river.he helicoidal motion of the flow aids the processes of hydraulic action and corrasion on the outside of the meander, and sweeps sediment across the floor of the meander towards the inside of the meander, forming point bar deposits.
Optic flow is defined as the change of structured light in the image, e.g. on the retina or the cameraâs sensor, due to a relative motion between the eyeball or camera and the scene.n the literature, the motion field is often confounded with the optic flow, which is defined by the temporal change of the registered patterns of light. The motion field as analytic model was formulated for a pinhole camera in locomotion.
